In this paper, the authors present highly robust Space Time Block Coded (STBC) multiple-input multiple-output (MIMO) system. This has been very popular in Long Term Evolution (LTE) and LTE-A (LTE-Advanced) plans. STBC along with MIMO has tremendous potential for link reliability in physical layer. Also looking at various methods of combining signals at receiver gives motivation to the use of MIMO in LTE systems. This paper discusses the combinations of multiple antennas at either transmitter and or receiver and shows that increase in number of antennas gives rise to Bit Error Rate (BER) which is one of the important measures of link reliability.
