A Parallel Bit Removal Greedy Algorithm for Multiuser 4G OFDM-based Systems Vrije Universiteit Brussel
Bit and power allocation remains a challenge inmultiuser multicarrier systems though optimal and suboptimal algorithms have been proposed. In this paper, we optimize the multiuser bit removal greedy algorithm by allowing removing bits in parallel, so reducing the computation time of the algorithm and making it attractive for real implementations. It has been proved that the proposed algorithm converges faster than both the traditional multiuser ...
