Abstract :
A wideband noncoherent multiantenna fading channel model in which the fading process exhibits both spatial and temporal correlation is analysed. By studying the derivative of mutual information at zero signal-to-noise ratio (SNR), the significant gain is achieved by increasing the number of transmit and receive antennas for MIMO channel.
