Echo Cancellation

Abstract

Multiple access communication, discussed in chapter 16, usually relies on the orthogonality of the different signals by separating them in time or frequency. Analogous techniques apply tofull-duplex transmission, or simultaneous transmission in both directions on a point-to-point link. Specifically, we can use time-compression multiplexing (TCM) and frequency-division multiplexing (FDM). A more efficient approach, echo cancellation enables transmission in two directions simultaneously using the same frequency band, thereby reducing the bandwidth requirements approximately in half relative to TCM and FDM.
