Abstract :
In this paper, we present the link level performance of SC-FDMA with SDMA (Space Division Multiple Access), real channel estimation and low complexity frequency-domain turbo equalization. We give the implementation of the minimum-mean-squared-error based turbo equalization which is suitable for DFT-S-OFDM based SDMA systems. The block error rate performance of SC-FDMA and OFDMA with SDMA and turbo receiver is compared under different code rate and modulation order.
