Falconer David Duncan, Mueller Kurt Hugo, Salz Jack, Spaulding David Adams: Joint equalization and carrier recovery adaptation in data transmission systems. Bell Telephone Laboratories Incorporated, Kearns J P, April 15, 1975: US3878468 (77 worldwide citation)

An adaptive transversal equalizer acts jointly with a phase-jitter compensator to achieve substantially jitter-free passband equalization of a suppressed-carrier coherent data signal without the use of transmitted pilot tones. The received signal is split into quadrature components for separate equa ...

Falconer David Duncan: Echo cancellers. Western Electric Co, October 16, 1981: FR2480534-A1

A full-duplex, two-wire Nyquist sampled data communication system includes an adaptive echo canceller (24) at each terminal (e.g., 10'). The echo canceller generates a replica (zm) of the echo component of each sample (rM) of the incoming signal. The replica and the sample are subtractively combined ...
