Optimization of Radio Resource Allocation

This paper addresses optimization of radio resource allocation for downlink Multiple Output-Orthogonal Division Multiple Access) Systems. It has an objective of maximizing the total system capacity and proportional fairness. The proposed algorithm determines the shortest path of subcarrier to each user and then handing over subcarrier to each user. The optimization methods used for radio resource allocation are Ant Colony Optimization (ACO), Subcarrier Allocation (SA) and Genetic Algorithm (GA). Simulation results show that the proposed optimization algorithm provides better performance by increased channel capacity and better fairness among users.
