Abstract

A low-complexity iterative receiver structure is proposed for a convolutionally coded system in a severe intersymbol interference environment where diversity reception is available. The receiver performs two successive soft decisions, first from a MMSE filter and then from a channel decoder. At each iteration, extrinsic information is extracted from the detection and decoding stages and is used as a priori information in the next iteration. Simulation results demonstrate that the proposed iterative receiver offers significant performance gain over traditional non-iterative receiver structures. Furthermore, the low complexity of the receiver permits its use in severemultipath channels (10 or more paths). (C) 2001 Elsevier Science B.V. All rights reserved.
