Abstract :
This paper introduces a combining algorithm for WCDMA handsets using a single front-end circuitry to enhance signal-to-interference-and-noise ratio (SINR). The proposed algorithm can have a gain of about 6 dB over selection diversity, the conventional design for multiple antenna system for handsets. Analytical equations based on a multipath channel model are derived and simulation results and performance evaluation comparing several diversity receivers are also presented
