Abstract :
Minimum mean square error (MMSE)-based multiple-antenna assisted co-channel interference suppression/space division multiple access (SDMA) schemes designed for OFDM have drawn wide interest. In this article, parallel interference cancellation (PIC) is proposed and studied in comparison to maximum likelihood sequence estimation (MLSE) based schemes. The best design trade-off was constituted by the successive interference cancellation (SIC) schemes
