In this paper, the capacity evaluation for multiple antenna receivers using the directional COST259 macrocell, general typical urban (GTU) channel model under different channel conditions will be studied. The statistical wideband channel model under consideration incorporates the properties of the impinging waves by a set of probability density functions (PDFs) and power spectra. The channel capacity represents the maximum number of information bits that can be reliably transmitted through the channel per unit time. Hence, the study of the information theoretic channel capacity can provide us with a measure of the performance of multiple antenna receivers. The capacity of the channel is evaluated by means of Monte Carlo simulation using a single-input multiple-output (SIMO) configuration at various channel conditions associated with delay spread (DS) and azimuth spread (AS). Our results show the significance of the AS as compared to the DS with respect to the system capacity. (4 pages)
