In this work we describe an optimization technique for multiuser resource allocation and adaptive modulation and coding (AMC) in OFDMA radio downlink communications. In particular, we propose an innovative AMC solution, based on M-QAM modulation and LDPC codes, jointly working with the scheduler and capable to maximize the achieved throughput while guaranteeing a given set of BER/FER requirements. Simulation results are presented to validate the proposed approach and a comparison with more traditional schemes is provided.
