碩士 === 輔仁大學 === 電子工程學系 === 97 === In this research, we present precise performance analysis with MIMO QAM systen in the presence of CCI and noise in several flat fading environments. In flat fading environments, ISI can be generated by co-channel interferers due to the random symbol timing and phase offsets between the desired signal and the co-channel interferers. The performances of the MIMO system with maximum-ratio (MRC) and optimal combining (OC) schemes in the presence of ISI due to co-channel interference (CCI) in flat fading channels is analyzed and compared. The interference impairment due to ISI made through computer simulation often will be very time-exhausting, particularly while multiple antennas is consider. In calculating the average accurate error rate, we use the Gaussian Quadrature Rule (GQR) method to obtain the accurate results efficiently.
