Performance analysis of turbo-equalized partial response channels

The performance of maximum-likelihood decoding of a serial concatenation comprising a high-rate block code, convolutional code, or a turbo code, a uniform interleaver, and a partial-response channel with additive white Gaussian noise will be addressed. The effect of a channel precoder on the system performance is also considered. Bitand word-error-rate estimates based upon properties of the average Euclidean distance spectrum of the coded partial-response channel are derived. The estimates are compared to computer simulation results, and implications for system design are discussed.
