Abstract

Resource allocation for orthogonal frequency division multiple access (OFDMA) systems which can effectively solve the signal distortion caused by the frequency-selective fading of the wireless channel and provide a high data transmission rate is a challenging issue for next-generation wireless communications. OFDMA is a multiuser OFDM system. It can adaptively allocate subcarriers based on different users’ channel conditions on different subcarriers and adjust power and number of bits on different subcarriers. In an OFDMA system, a proper resource allocation strategy can be used to optimize system performance within a limited spectrum while ensuring service QoS requirements. Therefore, designing an efficient resource allocation strategy for OFDMA systems is an important issue that is attracting attention in current mobile communications.
