Abstract

We modify the iterative soft-output Viterbi algorithm (SOVA) for partial response (PR) channels and examine its performance for parallel and serial concatenated codes on a precoded Class IV partial response (PR4) channel. We present a SOVA that differs slightly from what appears in the literature and compare the performance of the two versions. Code rates of the form k0/k0+1 (k0 = 4, 8, and 64) are considered. Our simulations indicate that the loss at Pb = 10-5 suffered by the SOVA, relative to the APP algorithm, is at most 1.2 dB for parallel concatenations and at most 1.6 dB for serial concatenations.
