DS/CDMA系统中多址干扰的消除
Co-Channel Interference Cancellation in DS/CDMA System
【摘要】 在直接序列扩频/码分多址(DS/CDMA)系统中由于各用户之间的影响而使其容量受到很大限制。通常这种用户之间的影响是作为噪声来处理的。本文讨论了多址干扰问题,从另一不同的角度出发,即把用户之间的影响作为有用信息,对多个用户的数据信息进行联合判决,提出了提高判决准确性的方案。
【Abstract】 In DS/CDMA multi-user system, the system capacity is limited by the interaction of signals from different users, which is termed as co-channel interference or multiple access interference and is generally treated as noise. In this paper, we discuss the problem from a different piont of view: using this kind of interaction as useful information, and propose a scheme to jointly decide data from all active users with improved decisive accuracy.
