Performance Analysis for Resource Allocation in OFDM with DAS

Abstract

this paper proposed on the improving of Energy efficient allocation of resources for OFDM systems. It is very complex to obtain efficient solution due to non-convex behavior of optimization problem. So we focused on implementation of low level complexity alternative optimal design. Allocation of subcarriers first will minimizes the complexity design, which is by assuming distribution of power equally. An equivalent optimization is developed by converting fractional form into subtractive form of non-convex optimization problem.
