空时信号处理在DS-CDMA中的应用

Application of Space-time Signal Processing in DS-CDMA System

在 CDMA技术中 ,可以用正交的编码方式来同时发送多个用户的信号 ,这可以增加发送空间的维数。这种CDMA技术往往结合直接序列扩频技术 ,这就是 DS CDMA。主要介绍了 DS CDMA的特征。在此基础上 。

CDMA refers to a method to transmit multiple users′ data simultaneously using coding,ideally orthogonal to add dimensionality to the transmit space. This CDMA technique is combined with Direct Sequence Spread Spectrum (DSSS) modulation to yield what is know as Direct Sequence Code Division Multiple Access Communication (DSCDMA).In this paper, the characteristic of DSCDMA are introduced.On the basis of this,the paper presents spacetime signal processing.
