The current Addis Ababa Long Term Evolution Advanced (LTE-A) network is being used to im-prove customer data service. Inter-Cell Interference (ICI), which is caused by a short inter-site distance paired with the use of frequency reuse factor one, has a major impact on mobile data network performance, particularly for users at cell edges. In order to mitigate ICI, the effect of Coordinated Multi Point (CoMP) on Cloud Radio Access Network (C-RAN) is investigated in this thesis. The concept behind C-RAN is to move traditional cell site digital baseband processing units and radio remote heads to the Base Band Unit (BBU) pool for centralized signal processing and management. C-RAN improves inter-cell interference with support of the CoMP technique in mo-bile networks, allowing for higher throughput. This is especially important as more additional base stations are deployed to increase mobile network capacity, allowing for effective interference man-agement to improve performance.To evaluate the proposed solution, the present Addis Ababa LTE performance is simulated while considering CoMP joint transmission with the C-RAN architec-ture. The network performance is evaluated for a specified test case area in Addis Ababa, taking into account actual base station locations and city terrain data.rnThe paper focused on ICI mitigation in the Addis Ababa LTE-A network. The Signal to Interfer-ence plus Noise Ratio (SINR), spectral efficiency, and system throughput performance metrics were used to compare and evaluate CoMP coordination and non-CoMP systems of various sizes. The simulation is implemented in MatLab, and network radio propagation is computed in WinProp. The simulation findings show that utilizing CoMP on C-RAN improves the signal to interference plus noise ratio and throughput for both average and cell-edge users significantly in comparison to traditional CoMP. In terms of employing a method to reduce the strongest interfer-ence, large-scale CoMP coordination is the most interesting. This confirms that it results in an improved cell average and cell edge of up to 193.5% throughput performance. As a result, it has been demonstrated that the proposed interference mitigation solutions significantly improve net-work performance and are suitable for deployment on existing Addis Ababa networks.
