Glenayre Electronics, Christensen O Connor Johnson & Kindness PLLC, July 13, 1999: US05923712 (61 worldwide citation)

A system for linearly transmitting an amplified output signal using predistortion whereby a straight inverse modeling scheme is used to more easily and accurately determine the inverse of the distortion caused by a power amplifier of a RF transmitter. The "inverse" of the power amplifier is directly ...
