Abstract: A baud rate error detection circuit has an edge detector, a start bit sampling circuit and an abnormal waveform detection circuit. The edge detector receives sync-field used for adjusting a baud rate of serial communication, and generates an edge detection signal in response to an edge included in the sync-field. The start bit sampling circuit measures a bit width of a start bit of the sync-field based on the edge detection signal and an internal clock signal, and generates an expected value signal indicating the bit width of the start bit as an expected value. The abnormal waveform detection circuit measures an inter-edge width after the start bit based on the edge detection signal and the internal clock signal, and generates an abnormal waveform detection signal if an error between the inter-edge width and the expected value indicated by the expected value signal exceeds a predetermined allowable error range.

Abstract: 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).
