Wireless communication systems at high data rates and low power consumptions are currently in high demand. Power efficiency becomes a critical issue for technology that will be used in 3G and 4G technologies. Orthogonal frequency-division multiplexing (OFDM) is a technique using discrete multi-tone modulation with each subcarrier modulating in a conventional modulation scheme. On the other hand, Multiple- Input Multiple-Output (MIMO) systems have become the attention of wireless academic community and industry because of the is promising ability to increase capacity and performance with acceptable Bit Error Rate ( BER) proportion ally with the increased number of antennas. Here, MIMO-OFDM system using Vertical Bell Lab Layered Space Time (V-BLAS T) is developed by considering Minimum Mean Square Error (MMSE) and Zero Forcing (ZF) detector mechanisms for various modulation schemes and different channel. The performance parameter of MIMO-OFDM in terms of BER is determined and an analyzed for six different detector schemes such as MMSE,MMSE-SIC,MMSE-SIC OPTIMAL ORDERING, ZF,ZF-SIC,ZF-SIC OPTIMAL ORDERING and with RICIAN and RAYLEIGH channel with the help of MATLAB package.
