Intersymbol interference (ISI) and co-channel interference (CCI) are two major obstacles to high speed data transmission in wireless cellular communications systems. Unlike thermal noise, their effects cannot be removed by increasing the signal power and are time-varying due to the relative motion between the transmitters and receivers. Space-time processing offers a signal processing framework to optimally integrate the spatial and temporal properties of the signal for maximal signal reception and at the same time, mitigate the ISI and CCI impairments.

Cooperative relay systems have emerged as promising techniques to boost the performance of wireless systems. Recent studies have confirmed that interferences, co-channel interferences (CCIs) and self-interferences, have a huge impact on cooperative relay systems and can cause significant performance degradation. Two problems were observed in this research. Firstly, previous studies on performance analysis of Amplify-and-Forward (AF) relay systems in presence of CCIs have only focused on a specific interference channel model. However, in practical design scenarios, such an assumption is not a r

Abstract:
碩士<br>大同大學<br>通訊工程研究所<br>99<br>The operator use&apos;s Cellular Network decrease Transmit power to increase the density of Base station and system capacity, but frequency reuse may cause the problem of co-channel interference more serious. The thesis focuses on investigating the distribution of base station in the area with serious interference to find the position of weak signal. By increasing the bandwidth to improve the problem of co-channel interference, and we can prove that it can decrease the problem of co-channel interference and increase the quality of signal via the actual measuremen
