Performance Analysis of Turbo-equalized Dicode Partial-response Channel

This paper addresses the performance of maximum-likelihood decoding of a serial concatenation comprising a high-rate convolutional code or a turbo code, a uniform interleaver, and a dicode partial-response channel. The e ect 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.
