Abstract:
The purpose of the present invention is to reduce the Peak to Average Ratio (PAR) of a transmission signal. A transmission device comprises a generation part for generating a cancellation pulse corresponding to a peak component of a transmission signal, and a cancellation part for attenuating the peak component using the cancellation pulse. In addition, the present invention includes some embodiments other than the aforesaid embodiment.
Abstract:
An apparatus and a method for operating a memory compensation Digital Pre-Distortion (DPD) are provided. In the method for operating a memory compensation DPD system, an input signal is received. An input average power of the input signal is determined. When the input average power of the input signal belongs to a non-linear section of the input average power, DPD is performed on a previous signal corresponding to a memory degree set depending on at least one non-linear section of the input average power.
