Abstract :
In this paper we evaluate the average throughput of two types of W-CDMA systems with Multiple-input-multiple-output and adaptive modulation and coding by numerical simulation and theoretic analysis. One system employs space-time transmit diversity, another implements per antenna rate control. In both systems the modulation levels and turbo coding rates are dynamically adjusted depending on the channel conditions. The channels are assumed to be Rayleigh fading channels. Closed-form expressions are derived for the average throughput of both systems. The simulation results prove the accuracy of the analysis.
