Resource Allocation Algorithm for the Downlink of Multi-User OFDM System with Optimized Fairness

Resource Allocation Algorithm for the Downlink of Multi-User OFDM System with Optimized Fairness

A resource allocation algorithm for the downlink of multi-user OFDM system with optimized fairness was studied. Firstly, assign the subcarriers to users with the constraint on proportional fairness and the water-filling algorithm was used in this process for the power allocation of each subcarrier....
