Iterative Layered Space-Time Receivers for Single-Carrier Transmission Over Severe Time-Dispersive Channels

Abstract

This letter presents an iterative layered space-time (LST) receiver structure for single-carrier (SC)-based transmission in severe time-dispersive channels. The proposed receiver combines LST principles with iterative block decision feedback equalization (IB-DFE) techniques. Our performance results show that the proposed receivers have excellent performance in severe time-dispersive channels, which can be very close to the matched filter bound (MFB) after just a few iterations.
