Abstract: The present invention relates to an input/output signal synchronization method by a radio frequency unit. The input/output signal synchronization method according to the present invention comprises the steps of: generating a transmitter (Tx) input signal by adding, to a baseband signal, a test signal located at a frequency out of an operation frequency range of the radio frequency unit; collecting the Tx input signal and a Tx output signal obtained by outputting the input signal through a Tx function block; and synchronizing the Tx input signal and the Tx output signals, based on a result obtained by the collecting.

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.
