Abstract :
In this paper, we derive a novel closed-form expression for the achievable average channel capacity of combined transmit and receive antenna diversity schemes on the downlink of wideband code-division multiple-access (WCDMA) third-generation systems. We consider open loop and closed loop versions of both maximal ratio combining (MRC) and selection diversity (SD), and study the impact of the various diversity combining schemes on the performance of WCDMA systems
