TDMA+TDD系统中高速无线数据传输的实现

针对浮空平台搭载的载荷重量、体积、功耗受限的问题，提出了一种时分多址结合时分双工的通信模式。使用该通信模式，网内所有节点均工作于一个频率之上，只需配备一套收发通道，解决了浮空平台载荷受限的问题。在此基础上，通过软硬件设计，实现了该通信系统的信号收发流程、帧协议和参数设置，并构造出一套完整的通信系统。仿真实验和实测结果表明，利用该方案构造出的通信系统较传统的频分多址通信方式在体积、重量、成本等方面均有优势，更适用于浮空平台的远距离、高码率传输。

Realization of high-speed wireless data transmission in TDMA+TDD system

For the problem that the weight,size and power consumption of the payload on floating platform are limited,a time division multiple access(TDMA) with time division duplex(TDD) communication mode is presented.All the network nodes are working on a frequency using this communication mode. Only one set of sending and receiving channel is required to solve the problem of limited load on floating platform.Then,through software and hardware design, the signal sending and receiving process, frame protocol and parameter setting are achieved. Compared with the traditional frequency division multiple access(FDMA) mode,the TDMA+TDD communication mode has the advantages in size,weight and cost. It is more applicable to the high bit rate transmission for long distance .
