Patent number: 7778350Abstract: Provided is a multi-carrier communication device capable of reducing the deterioration of a reception quality while suppressing the peak power of a multi-carrier signal. In this device, a clipping strain measurement unit (108) calculates the individual average powers (or the clipping strain powers) of peak suppression signals contained in a center area and in end areas. Moreover, the clipping strain measurement unit (108) uses the calculated clipping strain, to calculates the ratios of the signal powers to the clipping strain powers (or the ratios of the signals to the clipping strains) individually for the center area and the end areas, and outputs the calculated ratios of the signals to the clipping strains to a puncture-modulation mode selection unit (109).Type: GrantFiled: August 31, 2006Date of Patent: August 17, 2010Assignee: Panasonic CorporationInventors: Sadaki Futagi, Takashi Kitahara
