Downlink Throughput Statistics in interference-limited cellular systems based on Monte-Carlo Simulation Method

This paper considers the application of Monte-Carlo Simulation Method to quantify mean throughputs in interference-limited cellular systems along antenna pattern and frequency re-use factor. Firstly, we calculate the path loss between center cell to victim link receiver and all co-channel cells to victim link receiver to determine desired and undesired signals respectively. Next, AWGN and Shannon’s capacity have been used as a comparison to analyze the performance of throughputs in interference-limited cellular systems. The simulation results show that a re-use factor of N=1, directional antenna has improvement in the Shannon capacity by 242.2 % over Omnidirectional antennas whereas a frequency re-use factor of N=7 has increased to Shannon capacity by114% for N=7 over N=1.
