Abstract
A reduced complexity equaliser involving the novel reduced-state sequence estimation is presented. It is difficult to employ maximum likelihood sequence estimation for EDGE since it uses the 8PSK modulation scheme and hence high computational complexity is incurred. Consequently, a sub-optimum technique offering an approximation to the optimum performance is required. The proposed method is capable of equalisation with four states, at the expense of only 1dB trade-off in performance
