Analysis and simulations for ergodic capacity channel of MIMO systems
|
Abstract:
Under the assumption that the channel state information was available only at the receiver, the capacity of MIMO systems in Rayleigh fading channel was investigated on the basis of information theory. Three special expressions for the MIMO capacity over ergedic flat fading channel were derived. An asymptotic formula for MIMO systems with equal number of transmit and receive antennas in small SNR was also given. Simulation results show that this approximation is relatively accurate.
