Multiple-input multiple-output (MIMO) technology is a communication system to send and receive multiple antennas placed at both ends of a communication technology in recent years, theoretical research field of wireless communications is a major breakthrough. The technology can without increasing system bandwidth and transmit power of the premise that increases system capacity , improve frequency efficiency , to improve system performance , a new generation of high data rate wireless communication systems of multiple data types of key technologies. MIMO technology can usually be divided into spatial multiplexing ( MIMO improve the spectrum utilization efficiency advantages ) and spatial diversity ( MIMO is to improve the system reliability advantage) in two ways. Layered space-time coding is based on MIMO spatial multiplexing, space-time block code and space-time trellis code is based on the transmit diversity technique is based on diversity reception receive diversity technology. This mobile communication system for wireless transmission of information technology for the study focused on the multi-antenna technology, a number of theoretical performance of the system . Papers seven chapters , the main work is as follows : Chapter III study correlated MIMO system channel capacity ( including ergodic and outage capacity ) , presented at the different relevant conditions on the channel capacity for comparative research ideas , analyzes Rice fading channel capacity , also discussed with different transmission channel information system capacity ; fourth chapter analyzes the underlying MIMO system maximum ratio combining system outage probability and two fat collected ( or two close -prone ) system at different modulation mode of the system average error probability ; chapter 5, with co-channel interference single overcharged system transmission reliability , focusing on the unequal power with co-channel interference in the case maximal ratio combining technical performance analysis a variety of different types of desired signal fading and interference signal system ; sixth chapter discusses the relevance of the channel orthogonal STBC system capacity and performance , and gives very precise ergodic and outage capacity of approximate analysis ; in order to verify the correctness of the theoretical analysis , this paper through every part of the design of appropriate Monte-Carlo simulation , the actual numerical simulation and theoretical results are compared and analyzed .
