Authors(2) :-F. Preethi, X. M. Binisha

Multi Input Multi Output technology has attracted attention in wireless communications systems. To improve the reliability of wireless system depends on transmission rate, coverage and QOS. So that improving the rate of array gain, spatial multiplexing in diversity it can achieve the reliability. The theoretical performance of the Alamouti coordinate system code in time-varying Rayleigh fading channels without additional bandwidth and increased transmit power. It achieves the goal by spreading a similar total transmit power over the Associate in Nursing antennas to realize an array gain that improves the spectral potency and to realize a diversity gain that improves the link irresponsibleness. Multiple carrier block transmission with diversity gain could be a methodology with many benefits that are incorporated into standards. This project investigates the performance of multi antenna below spatial diversity using Alamouti signaling. This analysis totally characterizes by the variety, showing that it depends not only on the antenna configuration and channel memory, however conjointly on knowledge block length and knowledge transmission rate.
