Space-time code is a novel technology of code and signal process, which transmit and receive signal employ many transmit and receive antennas. Space-time code can improve the information capacity and data speed of wireless telecommunication system. 空时编码是无线通信的一种新的编码和信号处理技术,它使用多个发射和接收天线进行信息的发射和接收,可以改善无线通信系统的信道容量和数据速率。
In this system, it can complete self-positioning of base stations in frequency division multiplexing mode, by the principle of waveform memory. And the system can send the signal in code division multiplexing mode in theory, so it has a certain expansion of capacity. 水声定位信号收发系统采用波形存储的原理,能够完成在频分复用模式下基站的自主定位;同时在理论上该系统支持基于码分复用模式的定位信号的发射,具有一定的扩展能力。
