Resource Allocation Algorithm Based on Bandwidth Demands for OFDMA Systems with Imperfect Channel Quality Information

For the problem to maximize spectral efficiency of OFDMA-TDD systems while satisfying bandwidth demands and the average bit error rate (BER) constraints of users, a resource allocation algorithm based on bandwidth demands of users is proposed. The user weights are introduced and the Max weighted-SNR...
