Performance Analysis of Spatially Multiplexed MIMO using STBC Antenna Diversity Technique
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 7
Abstract
A new wireless broadband technology, MIMO (multiple input multiple output) systems, has gained great popularity for faster data transmission speed and have been actively investigated and successfully deployed for the emerging broadband wireless access networks. Even when a wireless channel with high channel capacity is known, we still require to find superior techniques to achieve high speed data transmission or high reliability. Multiple antenna techniques can be broadly classified into two categories: diversity techniques and spatialmultiplexing techniques. The diversity techniques intend to receive the same information-bearing signals in the multiple antennas or to transmit them from multiple antennas, in so doing improving the transmission consistency. A basic idea of the diversity techniques is to convert Rayleigh fading wireless channel into more stable AWGN-like channel without any catastrophic signal fading. When the spatial-multiplexing techniques are used, the maximum achievable transmission speed can be the same as the capacity of the MIMO channel; however, when the diversity techniques are used, the achievable transmission speed can be much lower than the capacity of the MIMO channel. Spatially multiplexed MIMO (SM-MIMO) systems with STBC antenna diversity technique can transmit data at a higher speed. Signal detection at the receiver side is a thought provoking task for SM MIMO systems. This paper addresses the performance of maximum likelihood detection, zero forcing algorithm and MMSE with successive interference cancellation using different methods of detection for SM MIMO systems.
