Abstract of the Disclosure In a receiver of the type adapted to receive bursts of signals sent at a predetermined rate of 1/T signals per second over a channel, wherein the receiver includes an automatic adaptive equalizer operative to facilitate accurate reception despite inter symbol interference when the signals each represent a predetermined number of data bits corresponding to a first selected high rate of data transmission, that improvement comprising circuitry for enabling the receiver to process during an early segment of a burst sig- nals each representing-fewer than the predetermined number of data bits, corresponding to a second selected rate of data transmission lower than the first rate, at which second rate the receiver is capable of accurate reception without complete adaptation of the equalizer, circuitry for using signals in the segment to adapt the equalizer in a decision-directed mode, and circuitry for enabling the receiver to process the signals at the first rate of data transmission upon completion of the adaptation.
