Equalization of the convolutional-coded Lorentzian channel

This paper presents simulation performance results of binary and ternary convolutional-coded Lorentzian channels at error rates of 10/sup -5/. The simulation results are compared with theoretical performance curves, and error propagation measurements are used to explain the discrepancy between predicted and measured performances for the decision feedback equalizer. Although noise correlation is a concern for partial response equalizers, simulations and estimated code performances suggest that the class IV partial response channel is a viable option.
