A Comparative Study of 1x1, 2x1 and 2x2 MIMO-OFDM Systems Based on IEEE802.16a

A comparison of 1x1, 2x1 and 2x2 multi-input multi-output (MIMO) – orthogonal frequency division multiplexing (OFDM) system based on IEEE802.16a, wireless Metropolitan Area Network (MAN) have been carried out by simulation of the systems in Matlab/Simulink. MIMO that refers to the use of multiple an...
