A Switching Mechanism Detection to Reduce Complexity in Multiuser Detection for DS-CDMA Systems

Rekha Agarwal, B. V.R. Reddy and K. K. Aggarwal

Abstract

We present a reduced complexity switching mechanism which uses either matched filter or Parallel Interference Cancellation (PIC) detector based on channel characteristics. The main criterion of taking PIC detector is that it has less Bit Error Rate (BER) and less processing delay than other nonlinear multiuser detectors. This proposed detector reduces overall complexity while maintaining the same performance as PIC detector. The switching mechanism is exploited by performance complexity tradeoff between matched filter detector and PIC detector.
