The vast usage of mobile applications have emerged a need for high speed data transmission and efficient and error free data transmission. For the purpose the use of multiple antenna systems at both the transmitting and receiving end is formulated known as MIMO systems. It provides improved spectral efficiency and link reliability as compared to conventional systems. When it is combined with OFDM systems; it eliminates the fading effect and with requirement of lower bandwidth it provides high throughput. Yet having a number of advantages; it suffers from some limitations like ISI, ICI and PAPR. These are the factors which degrades the system performance.
