Abstract:

 The wireless communication has derived to the present scenario after passing through number of stages and generation. From analog communication of 1st generation today we talk about digital communication in 4th generation, from the generation of single transmitting antenna and single receive antenna known as SISO systems, we reached the systems with multiple transmitting and multiple receiving antennas known as MIMO systems going through the systems of Multiple Transmit and single receive antenna systems known as MISO systems and Single transmit and multiple receive systems known as SIMO systems. This paper will present a study of generation from SISO systems to MIMO systems for digital communication under the research work going at Banasthali University, Rajsthan, India.

Index terms- MIMO, SISO, SIMO, MISO, MMSE, ZFE.
