Abstract

The performance of blind equalizers based on the adaptive tricepstrum (cepstrum of fourth-order cumulants) identification technique is examined. Comparisons with the performance of two existing blind equalizers are made. Multilevel pulse-amplitude-modulation signaling (2,4,8 levels) and additive white Gaussian noise conditions are assumed. It is demonstrated by means of Monte-Carlo simulations that the tricepstrum equalizer converges faster and with much lower start-up symbol error rate than the comparison schemes at the expense of higher computational complexity
