The paper considers the performance and design of a reduced complexity iterative equalizer, for a system including a rate one recursive channel precoder. Recursive channel precoders have been shown to yield significant performance gains in wireless communication systems, if designed correctly. Extrinsic information transfer (EXIT) charts are used to predict system performance and, as a configuration design tool, to determine powerful precoder and detector parameters. Bit error rate (BER) results for BPSK and 8-PSK modulation are presented, to verify the performance predictions of the EXIT chart analysis. Results show that even with large degrees of state reduction, the iterative receiver can achieve significant interleaver gain, associated with the inclusion of the recursive precoder.
