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

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.
