MIMO Rayleigh fading Channel Capacity

maximum capacity of a mimo channel is considered here.

In this code, we drive the Capacity of a MIMO system over Rayleigh fading
channel with different number of transmit and receiver antennas. For each
setting of a MIMO channel, after calculating the singular values of the
channel matrix, transmit power is distributed based on water-filling
algorithm. The obtained capacity is the best that MIMO system can deliver
as the full channel state information is used both at TX and RX side.
