ABSTRACT:
A passband echo canceller achieves improved performance by providing a signal having a substantially uniform power spectral density to an adaptive echo canceller; the improved input signal is substantially uniform from approximately zero hertz to one half the operating or sample frequency of the echo canceller. This signal may comprise that range of frequencies occupied by the transmitted spectrum with added out of band noise.
