  Abstract

This paper considers a communication system consisting of a vector quantizer with selected code vectors with mapped into points in the modulated signal space. The modulated signal is transmitted over a Rayleigh flat fading channel. We optimize the modulated signal constellation to minimize the overall distortion of the system with the fixed vector quantization codebook. The optimization is obtained by partitioning the modulated signal space. Simulation results show that the signal constellation based on the proposed optimization scheme outperforms the conventional methods.
