Abstract

A new scheme, selective time domain filtering, that has significantly reduced complexity compared to the SLM scheme, which only relies on conventional channel estimation and demodulation techniques for multipath fading channels to recover the data, is proposed. Computer simulations indicate that the new scheme suffers only a small loss in performance in exchange for significant reduction in complexity
