Joint chunk, power and bit allocation in OFDMA based LTE systems

Abstract

Orthogonal frequency division multiplexing (OFDM) is a key modulation technique to provide a high performance physical layer in modern wireless systems. Orthogonal frequency multiple accesses (OFDMA) is one of the best ways to resource allocations in OFDM systems. Resource allocation schemes are required to be optimized to improve performance of OFDMA based systems. Scope of this work is to study the performance of joint chunk, power and bit allocation in OFDMA based long term evolution (LTE) systems.
