  • Method of adaptively training an equalizer system of PAM-N receiver using training data patterns
    Patent number: 11765003
    Abstract: A method of adaptively training an equalizer system of a PAM-N receiver is disclosed. The method of training an equalizer system according to the present invention employs a training pattern including a first training data pattern and second training data pattern to tune the continuous-time linear equalizer, decision feedback equalizer and sampler constituting the equalizer system before use in actual communication enabling long-distance, high-speed communication.
    Type: Grant

  • PAM-N receiver capable of adaptively adjusting threshold voltages determining level of data in received signal and method of adaptively adjusting threshold voltages of PAM-N receiver
    Patent number: 11716229
    Abstract: A PAM-N receiver capable of adaptively adjusting threshold voltages determining a level of a received signal and a method of adaptively adjusting threshold voltages thereof are disclosed. According to the method of the present invention, the result of comparison between reference data levels and the level of data in the received signal are used to adjust the reference data levels, and the threshold voltages of a PAM-N receiver are adaptively calculated from the adjusted reference data levels, thereby reflecting transmission line conditions and Inter-Symbol Interference.
