Abstract
Conference Title: 2017 4th International Conference on Electrical and Electronic Engineering (ICEEE) Conference Start Date: 2017, April 8 Conference End Date: 2017, April 10 Conference Location: Ankara, Turkey This paper proposes subcarrier allocation to users in multi user OFDMA networks to fulfill the rate requirements and is considered as non linear optimization problem. In this proposed solution, subcarriers are allocated based on gain and data rate requirement of individual user, our simulation results have shown that, subcarrier allocation based on rate requirement and gain could lead to data rate maximization in the network. This fair allocation of Subcarriers can fulfill QOS requirements for all the users in the cell and could be maintained through out the connection life time.
