Unit 13Comparison between GSM and CDMA GSM与CDMA之比较Using CDMA/FDD technology, subscribers of CDMA cellular mobile communication system can transmit their information simultaneously through the same channel. On the other hand, the GSM system adopts TDMA/FDD method to transmit and distinguish information from different GSM mobile stations. In addition, in favor of QCELP arithmetic, RAKE receiver, power control and soft switching etc., CDMA shows more advantages in its system performance than the GSM, such as greater anti-interference capability, bigger system capacity, higher successful connection ratio, fewer off-line chances, low probability of intercept(LPI), and so on.使用码分多址/频分双工技术，用户的蜂窝移动通信系统的传输信息的同时，通过同样的渠道。
另一方面，该系统采用时分多址/频分双工传输的方法和识别信息从不同的移动台。
此外，有利于中国电信集团广州研发中心算术，耙式接收器，功率控制和软开关等，显示出更多的优势在码分多址系统性能比，如更高的抗干扰能力，更大的系统容量，连接成功率较高，离线的机会少，低截获概率（低截获概率），等。

Here are some key English terms used in the field of communication engineering:1. Bandwidth - The range of frequencies within a given band, used to measure the capacity of a channel to carry information.2. Bit Rate - The number of bits processed per unit of time, often measured in bits per second (bps).3. Carrier Signal - A wave that is modulated to transmit information, often a sine wave.4. Channel - A pathway for carrying signals, which can bea physical medium like a cable or a wireless frequency.5. Codec - A device or software that encodes and decodes digital data, often used in audio and video compression.6. Decibel (dB) - A unit used to express the ratio of two values of a physical quantity, often used to measure signal strength.7. Digital Signal Processing (DSP) - The use of digitalprocessing techniques to perform operations on signals that are in digital form.8. Encryption - The process of encoding messages or information so that only authorized parties can access it.9. Frequency Modulation (FM) - A method of transmitting information by varying the frequency of a carrier wave in proportion to the amplitude of the input signal.10. Hertz (Hz) - The unit of frequency, equal to one cycle per second.11. Interference - The unwanted superposition of one signal upon another, often causing a reduction in signal quality.12. Jitter - The deviation of the signal from its ideal timing, often a problem in digital transmission.13. Kilobyte (KB) - A unit of digital information equal to 1024 bytes.14. Laser - A device that emits light (or other electromagnetic radiation) through a process of optical amplification based on the stimulated emission of photons.15. Microwave - A type of electromagnetic wave with wavelengths ranging from one meter to one millimeter; often used for high-frequency communication.16. Network Topology - The arrangement of the elements (nodes, links, etc.) in a computer network.17. Optical Fiber - A thin strand of glass or plastic designed to transmit light signals over long distances.18. Protocol - A set of rules governing the format and transmission of data.19. QoS (Quality of Service) - The performance metrics ofa service, such as bandwidth, error rate, and latency.20. Radio Frequency (RF) - A rate of oscillation within the range extending from cycles per second to around 300 GHz.21. Signal-to-Noise Ratio (SNR) - A measure used in science and engineering that compares the level of a desired signal to the level of background noise.22. Transceiver - A combination of a transmitter and receiver in one unit, used for two-way communication.23. Uplink - The transmission link by which a mobile device sends signals to a base station or hub.24. VSAT (Very Small Aperture Terminal) - A two-way ground station that uses satellite for communication.25. Wavelength - The distance between two corresponding points in consecutive cycles of a wave.26. XDSL (Digital Subscriber Line) - A family of technologies that provide digital data transmission over the wires of a local telephone network.27. Yagi Antenna - A directional antenna consisting of elements in a line and usually used for receiving or transmitting radio frequency signals.28. Zigbee - A specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios.Understanding these terms is crucial for anyone studying or working in the field of communication engineering, as they form the foundation of the language used to discuss and develop the technologies that underpin modern communication systems.。

2.Fourier’s representation of functionsas a superposition of sines and cosines has become Ubiquitous for both the analytic and numerical solution of differential equations and for the analysis and treatment of communication signals 函数的傅里叶表示，即将函数表示成正弦和余弦信号的叠加，这种方法已经广泛用于微分方程的解析法和数值法求解过程以及通信信号的分析和处理。
3.If f (t ) is a nonperiodic signal, the summation of the periodic functions ,such as sine and cosine, does not accurately represent the signal. You could artificially extend the signal to make it periodic but it would require additional continuity at the end points . 如果f(t)是非周期信号，那么用周期函数例如正弦和余弦的和，并不能精确的表示该信号f(t)。

We haven't done any testing for three days, and I don't know how long this situation is going to last.我们已经3天没有开始正式测试了，我不知道这样的情况还会持续多长时间。
According to the original testing plan, we have to finish all the items by the end of next week. 根据之前双方的测试计划，我们下周末就必须完成所有条目的测试。
It's very urgent so I need you to make arrangements with the testing engineer from the operator. 这个非常紧张，所以需要你来协调局方测试人员的安排。
During the test today, the operator engineers mentioned one function that is very important to them and must be tested.今天测试过程中，局方提到一个功能，说对他们来说比较重要，一定要测试。
But our lab has already explained that the product doesn't support the function. I need you to discuss this issue with the operator.但是这个功能所内前期已经反馈不支持，需要你和局方进行协商。
I've discussed with the operator about this in detail during the testing today.今天测试的时候又和局方详细的沟通了一下。
The operator wants the hardware SN function. 局方想要的是设备的硬件序列号功能。
They want a unique serial number for every board. Even for boards of the same kind, the serial numbers have to be different.他们要求每个序列号对于每个单板都是唯一的，而且对于同一类型的单板，每块单板的序列号也都是要不同的。
The operator said that in this way they can collect and manage the data. And they will be able to know the exact location of each board. It'll make the management easier.局方说这样他们就可以将这些数据收集并管理起来，就可以知道具体那一块单板在哪个地方，便于管理。
In the earlier stage of testing, the operator required equipment with E1 uplink instead of IP uplink, so we can only provide the current equipment.本次测试前期，由于局方需要的是E1上行而不是IP上行的设备，导致只能选择现在这款设备来应对。
It has seriously affected our regular testing plan. We are one week behind the schedule.这已经严重影响到了正常的测试计划，我们比原先预定的测试计划延误了一周。
It is an old model and during the earlier stage of development, the chip doesn't support the hardware SN function.这款设备是比较成熟的产品了，在开发初期芯片还不支持这个功能。
The new model that we are developing now supports this function but doesn't support E1 uplink. 目前开发的新产品都是支持硬件序列号的，但是不支持E1上行。
It can realize a unique hardware type and serial number for each board. But for the boards of the same type, the serial numbers are the same.新产品能实现每块单板的硬件类型和硬件序列号，但是对于同一类型的单板，这个序列号是相同的。
Because of this the operator thought that we didn't meet their requirement.只是这样局方认为我们的实现不符合他们的要求。
The format was customized as the operator required. 局方要求的格式是定制的。
We did meet their requirement earlier but the operator testing engineer said there was an extra space after he checked it. We modified the format twice at the lab but both times there was an incorrect symbol.之前已经按照局方定制的要求实现了，但是局方看了后说是多了一个空格，后来家里改了2次，都有个符号不对。
:Now we have customized the format in full accordance with the operator's requirement.目前已经完全按照局方的要求定制好了。
And I've tested it myself. We can show it to the operator tomorrow morning.而且我也自测验证好了，明天一早就可以给局方演示。
We've finished testing all the items that can be tested today. Two items cannot be tested now. 今天我们完成了所有可以完成的测试条目，但是还有2个条目目前无法测试。
This time our narrow band voice service is connected with HW's softswitch via H.248 protocol. 我们本次窄带语音业务是和HW的软交换是按H.248协议进行对接的。
Formal testing started last Monday. 正式测试是在上周一开始的。
The basic services and some supplementary services have been tested and all have passed.基本的业务和一些补充业务都已经测试完成并通过了。
Only the third-party call and conference call were not tested because the softswitch hasn't been configured yet.只有三方电话和会议电话由于软交换上没有配置，无法进行测试。
I've talked to the maintenance person of HW for many times, but he didn't cooperate at all. I've also notified the operator of the situation many times.我已经和HW的维护人员沟通过很多次，但对方根本不配合我们，而且此事我也多次和局方测试人员进行通报。
The testing engineers of the operator can't help and they can't operate HW's softswitch equipment. Now we are stuck on this problem.局方测试人员目前也帮不上，而且局方测试人员也不会操作HW的软交换设备，所以目前就是卡在这个地方。
Really? Can you explain the situation in detail?是吗？具体的情况是什么样的，你详细给我说一下。
During our last meeting with the operator, it was confirmed that the testing engineer will fully cooperate with us and he wouldn't be given other tasks during the testing period.上次我们和局方的正式会议就确定了，局方测试人员的配合，局方领导说测试期间不会给该测试人员安排其他的工作。
I'll talk with the testing engineer's leader and find out what's going on.我和局方这个测试人员的领导沟通一下，了解一下局方那边的说法。
In addition, I'm going to visit the high level leaders of the operator tomorrow so I'll ask them to solve this problem and ensure the testing progress.另外我明天正好要去拜访局方的高层，我会再和局方的高层把这个事情落实好，保证我们的测试进度。
