Abstract
This paper proposes a unique low complexity semi-blind channel estimation and data detection receiver for downlink MC-CDMA systems. MMSE is combined with GMMSE and promising result is achieved. With the use of Partial MRC PIC scheme based on CQS, the performance of channel estimation and Multi-User Detection is improved and the system complexity is reduced at the same time. The simulation results indicate that our proposed system has a good BER performance and channel tracking ability in different channels and system loading conditions.
