In this modern communication world, wireless communication system is having a technique with high data speed in high robustness is used nowadays is MIMO-OFDM system. Over any network, the data speed cannot be achieved in over populated and congested network. These can be achieved by many researchers in many ways and it was represented in this article for the improvement of the network. As an issue or a problem cannot be solved practically in achievement of spectral efficiency, this will plays a main role in performance of a network. This extension of this review is to improve performance of network with concentration in throughput, PAPR reduction in network which is for MIMO-OFDM system. Further in this article, the review summary is provided how to improve the performance as channel selection in MIMO-OFDM system.
MIMO-OFDM system, Critical Review, Quality Improvement.
