摘要
在常规 M- ary扩频通信解扩解调方案的基础上 ,提出了利用虚拟匹配滤波器技术对多个携带数据流的扩频码同时进行相关解扩的思想 ,并对由此技术构成的 M- ary扩频通信的解扩解调方案进行了介绍。理论研究结果表明 ,此方案对 M- ary扩频通信的解扩解调是行之有效的。
Bascd on the traditional disspreading and demodulating scheme for M ary communication, the idea that the spread spectrum code of many data flows can be disspreaded at the same time is firstly presented by using virtual matched filter technology. Furthermore, the new disspreading and demodulating scheme based on this idea is also introduced and analyzed. Researching result shows that this new scheme is very valid for disspreading and demodulating of M ary communication.
