映射序列扩频通信方式及其特性

同时传送多路数据一直是通信的基本课题，本文提出用３个被调制的扩频序列处理成映射序列进行扩频通信，能同时传送３路信息数据，理论分析表明，在不改变常规扩频接收机的情况下，能可靠解出同时传送来的任何一路信息数据，它比８ＰＳＫ、８ＱＡＭ调制方式具有更好的通信特性。

Spread Spectrum Communication System and Properties Using Mapping Sequences

To transmit several data signals simultaneously is always one of the basic questions on communication for research. In this paper,we propose a kind of communication method which can transmit three data signals at the same time by transforming three modulated signals into mapping sequences before transmission.It's proved theoretically that such a method can demodulate any one of the data from the received signals without the change of normal spread spectrum receiver,it also present that the communication properties of this method is better than that of 8PSK and 8QAM.
