Nowadays the technology of the wireless communication is on the peak and the different research scholar are trying to show the solution of BER, ISI, and Power consumption, processing time reduction and capacity improvements. However, the wireless communication with a less distance can show the less complexity of the hardware but the big sized data is still a very severe problem for such cases. Wireless communication in the real time applications is severely affected by the fading due to the multipath propagation and the distance in between the transmitter and the receiver. Therefore, the different equalizers are used to recover the original bits. However, the effect of transmitting and the receiving antennas are also responsible in improving the capacity. Similarly, the OFDM channels or the subcarriers are selected in order to fight with the inter symbol interference (ISI). In this research paper, we have considered the MIMO in order to improve the capacity of our wireless system and different OFDM subcarriers in order to improve the bit error rate of the received bits. We are also using the Minimum Mean Square Equalizer (MMSE) in order to recover the bits and to decide the correct bits. Our simulation model can be tested on the latest MATLAB version and the comparative curves can be shown in favor of our statement Finally, the results can be shown in terms of BER and the SNR.
