ABSTRACT:
A terminal for a duplex transmission system for digital signals, which includes an adaptive quantized equalizer for reception and a pulse-shaping equalizer for transmission. The correction factors for the transmission equalizer are derived from the adaptively adjustable coefficients of the reception equalizer, the derivation being effected in accordance with recursive expressions which signify minimum intersymbol interference between successive pulses in a received digital signal.
