Abstract

A unified system model for multirate multiple-input multiple-output (MIMO) multicarrier code division multiple access (MC-CDMA) systems is proposed in this paper. Based on the proposed unified system model, a novel space-frequency minimum mean-squared error based successive interference cancellation receiver (SF-MMSE/SIC) is developed and analyzed. The signal processing of this new detector is jointly carried out in space and frequency domains, so the detector cancels the interference resulted from different sources simultaneously. Simulation results of the proposed detector are provided to demonstrate the good performance of the novel receiver. Our results also show that taking into account the subcarrier interleaving, VSF (variable spreading factor) scheme offers similar performance as that of multicode system.
