Lee Fang Wei: Technique for compensating for intersymbol interference. AT&T Bell Laboratories, R D Slusky, G A deBlasi, March 16, 1993: US05195107 (19 worldwide citation)

In a communications system, a generalized partial response signaling (GPRS) technique is employed to compensate for intersymbol interference. To this end, signal points representative of data to be transmitted are selected from a signal constellation. This signal constellation includes a multiplicit ...
