The purpose of the present invention is to reduce the Peak-to-Average Ratio (PAR) of a transmission signal. A transmission device includes 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.

Apparatus and method for reducing peak to average ratio in wireless communication system

A handover method of a mobile station in a wireless mobile communication system and a system therefore are provided. The mobile station transmits a handover indication message to a serving base station, receives a ranging response message that comprises authentication information required for the mobile station to authenticate a target base station, receives fast ranging resources and transmits a ranging response acknowledgement (ACK) message, which comprises authentication information required for the target base station to authenticate the mobile station, to the target base station after receiving the fast ranging resources. Accordingly, a handover break time is minimized.
