Abstract:
It is well known that the use of antenna arrays at both sides of communication link can result in high channel capacities provided that the propagation medium is rich scattering. In most previous works presented on MIMO wireless structures, Rayleigh fading conditions were considered. In this work, the capacity of MIMO systems under uncorrelated Rician fading is considered. We give closed form expression to evaluate the capacity for uncorrelated Rician MIMO case, which is quite simple to calculate as compared to the one obtained in [3]. In our calculations, it is assumed that the receiver has perfect channel state information (CSI) but no such information is available at the transmitter.
