摘要： A wireless transmission system capable of exerting a maximum path diversity effect by using combinations formed by symbol waveforms. A transmission timing controlling section (23) determines a transmission start timing. A modulating section (21) modulates a signal by using one of a plurality of symbol waveform candidates and by utilizing a modulation scheme in which a phase transition of a symbol waveform represents a waveform being changed, and then transmits the modulated signal at a transmission start timing. A predetermined delay amount is set such that (i) the number of reception timings, each indicating a timing at which a receiving station (12) receives a signal, is a plural number and is less than or equal to a maximum number of effective branches for each symbol waveform, and (ii) each time difference between the reception timings is greater than or equal to a delay resolution and less than or equal to a maximum delay.

摘要： An FFT unit (170) separates a received symbol by Fourier conversion into a plurality of subcarriers, and a phase difference detection unit (193) detects a phase difference between 4 pilot carriers and data carriers adjacent to the pilot carriers (adjacent carriers) The decision unit (194) decides whether the phase differences between the pilot carriers and the adjacent carriers detected by the phase difference detection unit (193) fulfill a phase difference condition. Then, the decision unit (194) decides that the received symbol is an HTSIG if the number of phase differences that fulfill the phase difference condition is greater than or equal to a predetermined number, and decides that the received symbol is either a SIG or a DATA if the number of phase differences that fulfill the phase difference condition is less than the predetermined number.

An error detector 11 detects an error of the output signal of the VCO 15. A voltage retainer 13 retains an output of a control voltage of the VCO 15. A reference signal generator 16 generates a reference signal. An adder 14 adds the reference signal to a control voltage outputted by the voltage retainer 13.

摘要： A wireless transmission system exerts a maximum path diversity effect even if the maximum number of effective branches is limited to a small number. A transmission timing control section determines a transmission start timing to be a timing obtained by delaying a reference timing by a predetermined delay amount. A modulation section modulates a signal by a modulation scheme such that an anti-multipath property is exerted when the signal is demodulated on a receiver side, and transmits the modulated signal at the transmission start timing. In a receiving station, a demodulation section demodulates the receive signal to obtain receive data. The predetermined delay amount is such that signals are received at the receiving station at a plurality of signal-receiving timings, and the number of signal-receiving timings is less than or equal to a predetermined maximum number of effective branches, a difference between the signal-receiving timings is greater than or equal to a predetermined delay resolution and is less than or equal to a predetermined maximum delay.
