发明名称 Method and apparatus for phase-noise compensation in digital receivers
摘要 A method and apparatus for compensation of noise in a received signal includes receiving a received signal comprised of a sum of a transmitted signal and a disturbance signal in a demodulator, summing the received signal and a compensation signal to produce a demodulation signal, determining a transmitted symbol based upon the demodulation signal, determining an error signal by calculating a difference between the demodulation signal and the determined transmitted symbol, and determining the compensation signal from the error signal using a model-based disturbance suppression control process. In at least one embodiment, the model-based disturbance suppression control process is a linear disturbance model control process.
