Abstract
A technique for reducing or eliminating effects of frequency and phase offset in a communications system includes implementing a demodulator having a Kalman filter based phase-locked loop for phase-shift keying or quadrature amplitude modulated signals. In an acquisition mode of operation, the Kalman filter based phase-locked loop continuously updates an error correction signal until an error between a received version of a predetermined signal transmitted using phase-shift keying or quadrature amplitude modulation and the predetermined signal is at or near zero. In a tracking mode of operation, the Kalman filter based phase-locked loop adjusts the error correction signal to maintain the error between the received signal and a predicted signal at or near zero.
