Abstract
The resource allocation problem for the downlink of Orthogonal Frequency Division Multiple Access (OFDMA) wireless multicast systems is investigated. It is assumed that both the Base Station (BS) and each user are equipped with a single antenna and the allocation unit is not the subcarrier, as in conventional OFDMA systems, but a set of contiguous subcarriers (chunk). The aim of the proposed efficient algorithm is to maximize the total throughput subject to constraints on total available power and average Bit Error Rate (BER) over a chunk. Simulation and complexity analysis are provided to support the benefits of chunk-based resource allocation to multicast OFDMA systems.
