Multiple-input-multiple-output (MIMO) is a communication technology that multiple antennas are set at transmitters and/or receivers. It is an important breakthrough in the area of wireless communication. The system capacity and frequency spectrum efficiency of communication systems can be improved by this technology without extra frequency bandwidth and with no additional power expenditure. MIMO is becoming a key technology of the new generation high data rate wireless mobile communication systems. MIMO generally has two kinds, spatial multiplexing (SM) and spatial diversity, layered space-time codes (LSTC) are a spatial-multiplexing technology, space-time-block-codes (SBTC) and space-time-trellis-codes (STTC) are the transmitted diversity technologies, and diversity combining is the received diversity technology.This paper investigates the technologies of wireless mobile communication systems, it mainly studies the theoretical performances of MIMO technologies. There are altogether seven chapters in the paper. Its main works are as follows: The ergodic capacity and outage capacity of correlated MIMO faded channel are given in Chapter 3, it gives an idea of comparing the channel capacity over some extremely correlated MIMO Rayleigh fading channels, and this chapter also discusses the channel capacity of correlated Rician MIMO fading channel and waterfilling algorithm. The outage probability of correlated MIMO Rayleigh fading channel is presented in Chapter 4, and it also gives the bit error rate and symbol error rate of different modulated schemes over two-input-multiple-output (or multiple-input-two-output) systems. Chapter 5 analyzes the performance of single-input-multiple-output systems with multiple co-channel interferers (CCI), it mainly studies the performance of unequal power CCI cases with different fading channels. The channel capacity and system performance of orthogonal space-time block codes (OSTBC) are given in Chapter 6, it also presents an useful approximation method to analyze the system ergodic capacity and the capacity...
