Review on MIMO System using Transmit Diversity and Relay Selection Algorithm

MIMO for wireless communication is an antenna based technology where multiple antennas at each end are used to minimize the errors, optimize speed and data integrity also it meant for improvement of the efficiency and reliability of a system. Conventional technology which use single antenna at both source and destination results in problems such as fading, cut-off, intermittent reception. To extend coverage area, data rate, quality of service etc. several systems have been come up with goal of low complexity and having high gain. We present here a comprehensive review of MIMO System Using Transmit Diversity and Relay Selection Algorithm where Transit Diversity technique used to improve the wireless link performance and received signal quality whereas Relay Selection are used for interference suppression. MIMO system enables to increased spectral efficiency and by using MMSE estimator it results in minimization of mean square error.
