Abstract
A data-driven echo canceller for full-duplex data transmission with multitone modulation is presented. This echo canceller is shown not to be impaired by the eigenvalue-spread problems that are inherent in signal-driven echo cancellers, and to have numerical performance and cancellation range that equals, and in most cases exceeds, that of data-driven echo cancellers used in data transmission with baseband or quadrature amplitude modulation. The method makes use of frequency-domain updating, but with time-domain implementation of the canceller. It introduces no delay into the received signal path.<>
