Abstract
A transceiver system compensates for baseline wandering in an analog signal in the analog stage before sampling the analog signal and processing the analog signal in the digital stage. The transceiver system includes an analog to digital converter that samples the analog signal after baseline wandering compensation, a digital equalizer to condition the digital samples, and the slicer to determine transmitted symbols from the digital samples. The transceiver system includes a subtraction block that determines the difference between an input and an output of the slicer, a digital to analog converter that converts a difference between the input and the output of the slicer, a low pass filter that filters out high frequency components of the difference between the input and the output of the slicer thereby to extract out the baseline wandering, and a signal summation circuit that subtracts the baseline wandering from the analog signal.
