Optimal power-and bit-loading in a multitone system requires prohibitive nonlinear programming. A useful near-optimal solution has previously been proposed which imposes a uniform error probability distribution across the tones. In this paper, we examine two alternative near-optimal solutions and offer a comparison with the existing solutions. The first imposes uniform power across the used tones and optimizes the bitloading and error probability distribution. The second is a default scheme in… CONTINUE READING
