四. iDEN 使用的先进技术
iDEN(integrated Digital Enhanced Network)是一个共用频 率,作指挥、调度用的专用数字集群通信系统。它采用时分 多址(TDMA)技术、VSELP(Vector Sum Excited Linear Prediction)矢量和激励的线性预测编码技术和抗干扰能力 强的M-16QAM(Quadrature Amplitude dulation)正交振幅 调制技术,并采用了和GSM 系统相同的双工通话结构以及特 殊的频率复用方式,使系统具有低功率、大容量、广域覆盖 的特性。

二. iDEN 在世界的应用
目前在北美、南美及亚洲十三个国家投入商业应用。全球iDEN 用户已超过 1000万。摩托罗拉的iDEN 系统在亚洲也取得了巨大发展,其中包括与 韩国仁川国际机场,中国深圳和上海等有关单位签署的合同以及在日本、 菲律宾、韩国,新加坡和中国福建等地正在运行的iDEN 网。
三. iDEN 在中国的应用
