Lte Mimo Optimization Pdf Mimo Telecommunications Engineering In this paper, we analyze the capacity of multiple input multiple output (mimo) rayleigh fading channels in the presence of spatial fading correlation at both the transmitter and the receiver, assuming that the channel is unknown at the transmitter and perfectly known at the receiver. A simple closed form expression allows for tight approximation for the achieved capacity of the massive mimo osgd system and an accurate approximation formula describes the rate outage probability of this system.
