Abstract
The EUTRA network offers significant data throughput rate. In this paper, we study and investigate the performance of Proportional Fair (PF) algorithm for media access control scheduler in Long Term Evolution (LTE) network and proposed an Optimized Proportional Fair (OPF) Algorithm. Furthermore, we implemented both algorithms and measured Key Performance Indicator (KPIs) as UE throughput (peak, average, and edge), average spectral efficiency and Fairness Index. On comparing the performance of proposed OPF algorithm with existing PF algorithm , we observed that on decreasing resource distribution by 14–15% in PF algorithm, proposed OPF algorithm show improvement of 4.7% in spectral efficiency, 54% in UE Peak level throughput, 15% in UE Average throughput, 15% in cell average throughput and degradation of 7% margin in UE Edge throughput. In this paper, we conclude that proposed OPF algorithms improve the performance of LTE EUTRA network. As the further scope of work, we suggest improving the performance of the UE at edge level throughput.
