Abstract

Group of synchronous code barker code in digital communication system and the characteristics of the principle of barker code recognizer is the soul of the whole design, was given by using the dynamic communication system simulation software SystemView simulation design and analysis method of barker code recognizer. The principle of PN sequence generator and the working process of the barker code recognizer, using dynamic communication system simulation software SystemView designed by data generator, clock generator, PN sequence generator, 8 bits shift register, adder and logic in the composition of the comparator barker code discriminator circuit simulation, and the simulation of the glyphs in the process of parameter setting and barker code to generate the waveform, barker code recognition output waveform, pulse single-peak detector, data and clock waveforms overlay, etc. The results of simulation analysis. Finally, the system performance index missed synchronization probability and false synchronization probability, group of synchronous average set up time and group synchronization protection. The simulation results show that the method is feasible and effective.

Key words: The System View.Barker code recognizer; The simulation design; Group synchronization code.
