Abstract
A continuous adaptive modulation multitone system for multipath fading channels is shown. To obtain a target BER and maximum aggregated rate. Each subcarrier bit rate is modified independently to adjust the transmitted signal to the spectral channel shape and to track the channel variations dynamically. Spectral efficiency and the required feedback channel capacity are obtained through simulation over a multipath Rician channel
