无线通信 TD-LTE简介
多用户通信实现的本质就是把可用的资源划分成多个相互正交的资源（互不重叠，或互不相同，或互不干扰的资源）频域资源划分 —FDMA传统的FDMA的频率间隔最小为2× 1/T，“资源互不重叠，互不相同”
OFDM频率间隔为1/T，资源部分重叠，但互不干扰；
时间资源划分 —TDMA，资源互不重叠，互不相 ...

OA系统 通信标准研究与开发是通讯行业的制高点。当前发展最为兴旺
通信标准研究与开发是通讯行业的制高点。当前发展最为兴旺，潜力最大的莫过于3gpp的3.9G无线通信标准——LTE。本代码实现了从3gpp网站直接下载标准会议提案，配合LTE会议报告轻松获取感兴趣的标准提案，加快工作流程
邮电通讯系统 把地理区域分成一个个小区
把地理区域分成一个个小区，蜂窝系统在该区域内提供无线覆盖。把可用的频谱分成很多信道，每个小区分配一组信道。使用频分双工（FDD）。在小区间进行频率利用，N个小区构成一个簇，簇间进行频率复用。定义了传播特性（信道参数）以及同频小区的位置。信道的参数包括：小区半径，路径损耗指数，以分贝为单位的对数正态阴影的 ...
