Review on multiple input multiple output antenna systems design

Considering the advantages of multiple inputs multiple outputs (MIMO) over the single input single output system (SISO), authors have developed various techniques to implement the designs for various applications. In this review paper, a brief investigation has been done on the effort done in last decade. In wireless MIMO both the transmitting and the receiving end is equipped with multiple antenna elements. Various authors have exposed the philosophy behind MIMO system. In that they have elaborated that the transmitting antennas and receiving antennas are jointly combined in such a way that fading will decrease and the bit transfer rate will increase so at the receiving end we will get high signal to noise ratio (SNR). At the system level, careful design of MIMO signal processing and coding algorithms can lead to an increase in the capacity and coverage.
