Abstract :
An analytical model for the evaluation of HSDPA capacity is proposed and used to carry out a comparison of several MIMO systems. HSDPA is an evolution of the UMTS standard over the air interface to achieve higher aggregate bit rates through the introduction of adaptive modulation and coding, hybrid ARQ, fast scheduling, fast cell selection and MIMO (space time coding and Blast) techniques. The model is used to compare MIMO systems, a typically difficult task to provide some insight. The results are supported by a simulation.
