English Abstract

Mobile operators are happy with the increasing number of users, but on the other hand, they are under pressure to satisfy the huge requirements of the data rates and enhance the network quality of service. A coordination technique between more than one cell sector called Coordinated Multipoint (CoMP) transmission and reception is one solution to enhance the service. CoMP is used to improve the cell edge throughput, improve the average data rate, mitigate the interference and increase the spectral efficiency. In CoMP, base stations cooperatively process User Equipment (UEs) connected to multi-points to eliminate the inter-cell interference. The cell edge UEs can be served in CoMP by more than one sector, so CoMP networks convert the interference signal into useful information by controlling the interfering signals among adjacent cells. This thesis proposes some key research directions and deployment issues such as different types of clustering and optimization criteria, also investigates how CoMP communications can enhance the spectral efficiency and Signal-to-Interference and Noise Ratio (SINR) in inter-site and intra-site CoMP. In addition, we study CoMP static clustering technique and applying different optimization criteria to enhance clustering selection methodology in both ideal and practical cases. Special emphasis is given to practical implementation by considering both inter-site and intrasite CoMP. Also we propose sectors weighting function according to the average number of sector connected users which can reduce the error of uniform UEs assumption and evaluate the performance of practical CoMP network. We consider Al-Khobar city topography and terrain data to simulate the received power and SINR behavior in specific cases. Practical network deployment is utilized to show SINR improvement in CoMP networks. The conducted research shows that practical CoMP networks can enhance the system SINR to similar level as in ideal CoMP networks, despite of the non-uniform distribution for UEs and BSs. This work also proposed a cluster selection algorithm based on SINR threshold values for the ideal networks and a quality weight function in practical network that increase the utilization of practical network resources.
