Dion M Funderburk, Sangil Park, Garth D Hillman: Circuit and method for phase error correction in a digital receiver. Motorola, Elizabeth A Apperley, September 28, 1993: US05249204 (16 worldwide citation)

A digital receiver, such as "C-QUAM" receiver (10), has phase error correction. In another form, a software program may be executed by a conventional digital signal processor to also implement phase error correction. A digital input signal is demodulated to form an in-phase and a quadrature componen ...
