A. Gutierrez et We. Ryan, Performance of Volterra and MLSD receivers for nonlinear band-limited satellite systems, IEEE COMMUN, 48(7), 2000, pp. 1171-1177
This paper evaluates the performance of Volterra equalizers and maximum-lik
elihood sequence detection (MLSD) receivers for compensation of signal dist
ortion in nonlinear bandlimted satellite systems. In addition, the performa
nce of a receiver with a fractionally-spaced equalizer followed by a Volter
ra equalizer is studied (FSE-Volterra equalizer), For the equalizers, adapt
ation of the equalizer weights is considered including a multiple-step LMS
algorithm which improves the convergence characteristics. Two MLSD receiver
structures are considered: the optimum receiver consisting of a matched-fi
lter bank followed by a Viterbi detector and a suboptimum receiver consisti
ng of a single receiver filter followed by a Viterbi detector. The performa
nce of the MLSD receivers is then compared to that of the equalizers.
