Abstract
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.
