This paper investigates the capacity of discrete time uncorrelated Rayleigh fading multiple input multiple output (MIMO) channels with no channel state information (CSI) at both the transmitter and the receiver. We prove that to achieve the capacity, the amplitude of the multiple input needs to have a discrete distribution with a finite number of mass points with one of them located at the origin...
The mutual information of a discrete time Rayleigh fading channel is considered, where neither the transmitter nor the receiver has knowledge of the channel state information (CSI). We show the mutual information of uncorrelated multiple input multiple output (MIMO) Rayleigh fading channels in closed form when the input distribution is complex Gaussian for any transmit and receive antenna configuration...
The mutual information of a discrete time Rayleigh fading channel is considered, where neither the transmitter nor the receiver has the knowledge of the channel state information. We specifically derive a lower bound for the mutual information of this channel when the input distribution is Gaussian. The bound is expressed in terms of the capacity of the corresponding non fading channel and the capacity...
Limits of information transfer over a discrete time uncorrelated Rayleigh fading MIMO channel is considered, where neither the transmitter nor the receiver has the knowledge of the channel state information (CSI) except the fading statistics. We show the capacity supremum with the receive antenna number at any SNR using Lagrange optimisation. Furthermore, we show the asymptotic capacity when the input...
