Abstract:
1. A communication signal receiver, comprising: a first adder, performing an addition on a first signal and a filtered signal to generate an output signal; a slicer, coupled to the first adder, performing a hard decision on the output signal to generate a detecting result; an infinite impulse response (IIR) filter, coupled to the slicer and the first adder, processing the output signal to generate the filtered signal; and a selector, coupled to the slicer and the IIR filter, selectively outputting the output signal or the detecting result to the IIR filter according to a control signal, wherein when the selector outputs the output signal to the IIR filter, the IIR filter processes the output signal to generate the filtered signal, and when the selector outputs the detecting result to the IIR filter, the IIR filter processes the detecting result to generate the filtered signal; wherein the selector outputs the detecting result to the IIR filter first and then outputs the output signal to the IIR filter according to the control signal.
