This paper has presented capacity analysis of multiple antenna wireless system under different array and channel configurations. In this study, the dimension of conventional multiple input multiple output (MIMO) system was extended to large scale MIMO. The capacity of MIMO system was considered over spatially correlated Rayleigh channel. The parameters of interests used for the system analysis are the channel capacity (measured in terms of data transfer rate) in bit per second/ hertz (bps/Hz), signal to noise ratio (SNR) in dB, spacing between the antennas, and the number of antenna elements. A MATLAB model was developed for the system for the purpose of simulation analysis to examine channel capacity performances under different antenna arrangement and channel configurations. Simulation results revealed that the capacity of the system increases as the number of antennas at both transmit and receive ends increases. Generally, the uncorrelated channel provided better capacity than correlated channel in all cases. However, the capacity of the correlated channel offers more practical results than uncorrelated channel.Keywords
