Robert L Farah, Stephen M Walters: Bit compression coding with embedded signaling. AT&T Bell Laboratories, John K Mullarney, Thomas Stafford, May 7, 1985: US04516241 (30 worldwide citation)

A bit compression coding circuit incorporates signaling bit insertion. An input signal sample(s) representing, for example, PCM encoded speech or voiceband data, is delivered to a difference circuit (31) where a predicted signal (s.sub.e) is subtracted from it. The predicted signal is an estimate of ...
