A New Computationally Efficient Discrete Bit-Loading Algorithm for DMT Applications

IEEE Transactions on Communications, Vol. 53, No. 5, May 2005, pp. 785-789.

Abstract: This letter presents a new bit-loading algorithm for discrete multitone systems that converges faster to the same bit-allocation as the optimal discrete bit-filling and bit-removal methods. The algorithm exploits the differences between the subchannel gain-to-noise ratios in order to determine an initial bit-allocation and then performs a multiple bits loading procedure for achieving the requested target-rate. Numerical results using asymmetric digital subscriber test loops demonstrate the computational efficiency of the proposed algorithm.
