The relation between the number of antennas and system capacity at a given SNR was also analyzed. The numerical results present that the capacity is degressive for MMSE MUD, MLD with interference covariance known, MLD with interference covariance unknown, and decorrelating detector, furthermore the three latter detectors all have platform as SNR is large; at a given SNR, the relation of system capacity and the number of antenna is linear for a NXN system. %K Capacity of MIMO channel %K Multipath fading channels %K Walsh codes
