摘要

本文推导了过饱和同步CDMA系统中预编码韦尔奇界签名集的信干扰比。为此，给出了一种新的CDMA预编码定义，并给出了一般的相关结果。结果表明，在使用常规接收机的情况下，带预编码的系统比不带预编码的系统性能更好。

Precoding Welch-bound signature sets

In this paper signal-to-interference ratio for precoded Welch-bound signature sets is derived for oversaturated synchronous CDMA system. For this, a novel definition for CDMA precoding is given and a general correlation result is presented. It is shown that the system with precoding outperforms the system without it, assuming that conventional receiver is used.
