Abstract

A channel optimized vector quantizer (COVQ) is studied for the case of transmission over waveform channel. In this work, a number of modulation schemes with multidimensional signal constellations are considered, specifically, results on the binary signaling, M-ary phase-shift keying (MPSK) and M-ary quadrature amplitude modulation (MQAM) performance using COVQ over a waveform channel are provided.The proposed system, based on COVQ with hard-decision decoding, is optimized for additive white Gaussian noise (AWGN) and flat-fading Rayleigh channels. In addition, when flat-fading Rayleigh channel is assumed, diversity techniques are used and evaluated to improve the performance of the system.
