  • Apparatus and method for transmitting signal in wireless communication system
    Patent number: 10644658
    Abstract: The present disclosure relates to an apparatus and a method for transmitting a signal using a power amplifier in a wireless communication system in which a transceiver comprises a digital pre-distorter configured to distort an input signal based on a distortion control value, a power amplifier configured to amplify an output signal from the digital pre-distorter, an antenna configured to transmit an output signal from the power amplifier, an echo signal canceller configured to remove an echo signal which returns to the power amplifier due to a return loss of a path between the power amplifier and the antenna, from a feedback signal obtained at an output stage of the power amplifier, and a digital pre-distortion adaptation unit configured to determine the distortion control value based on an output signal from the echo signal canceller.

  • Method and apparatus for canceling a peak of an input signal
    Patent number: 9363113
    Abstract: A method for removing a peak of an input signal includes forming a peak group including multiple peaks having an amplitude greater than a preset signal threshold value in the input signal, generating a cancellation pulse corresponding to the peak group, and generating a output signal by subtracting the cancellation pulse from the input signal.
