Abstract

In this article a multiuser receivers for DS-CDMA frequency-selective fading channels using linear matrix inequalities (LMI) is proposed. The filter of the Rake decorrelating detector (RDD) is used for the optimization process. The performance of the system is given by the bit error probability. The results shown that the LMI filter achieves the performance of the optimal detector.
