Abstract

In this work, we extend the LMMSE multiuser detector to multi-rate CDMA systems, where different users have different quality-of-service (QoS) requirements. The proposed LMMSE detectors can work on dual-rate mode according to different computational constraints. Only the signature of the desired user is needed in using the proposed multi-rate LMMSE detectors. The proposed detectors have better detection performance and less computational requirement than the dual-rate decorrelating detectors. Computer simulations verified analytical results and conjecture.
