Abstract: A mirror sub-carrier demodulation circuit includes a waveform generation unit, which generates a composite waveform of received I and Q signals, and a peak detection unit, which detects peak values of the composite waveform generated by the waveform generation unit. The demodulation circuit also includes a peak interval detection unit, which detects an interval of the peak values detected by the peak detection unit and generates timing at which the received data is input. The demodulation further includes a temporary storage unit, which stores I data and Q data at the timing generated by the peak interval detection unit, a calculation unit, which performs a correlation calculation using the I data and the Q data of the temporary storage unit acquired during a 1-bit period on the basis of a setting value M of a mirror sub-carrier, and a data determination unit, which determines data of 0 or 1 from the result calculated by the calculation unit.

Abstract: In a synchronous detection circuit, an interpolation circuit regulates an interpolation calculation coefficient based on phase shift information when carrying out interpolation calculation processing over a digitally converted received signal. A sampling circuit samples interpolation data using a recovered clock as a reference and two clocks having phases which are advanced and delayed with respect to the recovered clock. A phase shift detecting circuit monitors a phase shift using three sampling data output from the sampling circuit and outputting phase shift information to the interpolation circuit when detecting a predetermined phase shift. A demodulating circuit performs demodulation processing using the data subjected to the sampling with the recovered clock output from the sampling circuit. Where a synchronous shift is detected, the interpolation circuit performs regulation to match a timing having a maximum signal-to-noise ratio and the recovered clock based on the amount of the phase shift.

Abstract: A diversity wireless device for use in a wireless terminal unit includes at least one grounded antenna and at least one ungrounded antenna in proximity to each other on a circuit board. By providing at least one ungrounded antenna and at least one ground antenna, there is low correlation between antennas resulting in a high diversity gain. The high diversity gain as a result of these antennas is maintained even with downsizing of the diversity wireless device.
