Abstract:

In this paper, an efficient bit-loading algorithm is proposed for HPAV specification, aiming at maximization of data rate under the constraint of transmission power spectrum density and bit error rate. The algorithm is based on preallocation and adopts a new iterative method to reduce computational complexity. Simulation results show that the proposed algorithm can achieve optimal allocations while computational complexity is about half of existing methods.
