الملخص

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