SUMMARY
Performance limits of information transfer over a discrete time memoryless Rayleigh fading channel with
neither the receiver nor the transmitter knowing the fading coefficients except its statistics is an important
problem in information theory. We derive closed form expressions for the mutual information of single input
single output (SISO) and multiple input multiple output (MIMO) Rayleigh fading channels for any antenna
number at any signal to noise ratio (SNR). Using these expressions, we show that the maximum mutual
information of non-coherent Rayleigh fading MIMO channels is achieved with a single transmitter and
multiple receivers when the input distribution is Gaussian. We show that the addition of transmit antennas
