摘要： A method and control system for controlling output signals of a system comprising a first and a second dynamic system, which receive a first and second input signal and output a first and second output signal, respectively. The method involves using a first control system to generate first control signals to compensate for the first and second output signals based on the difference between the output signal and a reference signal. A second control system generates one or more second control signals based on the difference between the first and second output signals. The second control signal is used for further compensating the output signals, and/or the first control system further compensates the output signals based on the second control signal. The first and second control systems have different closed-loop bandwidths, with the second being smaller than the first.

摘要： An optical receiver (1) detects a clock phase of a signal in a time domain whose number of samples has been adjusted, estimates a clock frequency difference from a received signal using a detection value of the clock phase, determines a sampling phase for each FFT depending on an estimation value of the clock frequency difference, selects from a coefficient LUT a filter coefficient associated with a delay amount corresponding to the sampling phase, and multiplies a signal divided by a division unit with the selected filter coefficient.
