The capacity of Gaussian broadcast MIMO channel can be improved with dirty paper coding. In this paper, the mean capacity for MU-MIMO (Multi-User Multiple Input and Multiple Output) is analyzed in terms of number of frames, available number of users at mobile station and number of packets. The analysis is done for 4x4 matrix. Dirty paper coding improves the degradation due to correlation and mutual coupling. In multi-user communication, multiple antennas allow users to transmit their data stream in the uplink and downlink.
