Abstract :
This paper presents the performance analysis of optimum transmission (OT) and maximum-ratio transmission (MRT) for multiple-input/multiple-output (MIMO) systems subject to cochannel interference (CCI). We consider digital cellular mobile radio systems with quadrature amplitude modulation (QAM) transmission operating over both nonfading and flat Rayleigh fading channels. Our analysis accounts for pulse waveform and modulation of the desired signal, as well as cochannel interference (CCI). The phase delay between the desired signal and CCI, which can result in symbol timing and phase offsets for each receiving antenna element, are taken into account. A Gaussian interference model is also considered for a comparison with the precise interference model in the MRT based MIMO systems.
