Simulation study of WiMAX base station deployment using AMC under different frequency planning techniques
WiMAX base stations are deployed in cellular network to increase the coverage area and capacity. Inter cell interference (ICI) is a major problem in cellular network. Different frequency planning techniques are proposed to handle the ICI effect such as frequency reuse of one (FR-of-1) and fractional frequency reuse (FFR). In this paper, these two types of network deployments are implemented, analyzed, and compared in a grid of 19 base stations, where band adaptive modulation and coding (band-AMC) is used in each cell. Users are randomly distributed in the target cell, and their resource and burst profile selection are determined based on the reported signal to interference plus-noise ratio (SINR). The simulation results proved that FFR shows better performance than FR-of-1 in terms of variety of metrics. FFR enhance the number of served users and resource utilization to 96.42 %, compared to FR-of-1 where only 77.77 % of resources are exploited. The data rate has been increased to 8.280 Mbps under FFR, whereas in FR-of-1 it reaches to 7.277 Mbps. The spectral efficiency in FFR equals to 0.619 Mbps/Hz, whilst it increased to 0.977 Mbps/Hz in FR-of-1, since the latter exploits all the available bandwidth unlike FFR where part of the bandwidth is not used in each cell edge. This work reveals that FFR can enhance the performance of WiMAX base station in an interference environment more than that in FR-of-1, which makes FFR a strong competitor for deploying WiMAX base stations in such environment.
