WIRELESS TRANSMISSION SYSTEM AND WIRELESS TRANSMITTING METHOD, AND WIRELESS STATION AND TRANSMITTING STATION USED IN THE SAME

摘要

The present invention provides a wireless transmission system capable of exerting a maximum path diversity effect by using combinations formed by a plurality of symbol waveforms even when a maximum number of effective branches is limited to a small number. A transmission timing controlling section (23) determines a timing delayed from a reference timing by a predetermined delay amount as a transmission start timing. A modulating section (21) modulates a signal, by using one symbol waveform among a plurality of symbol waveform candidates, utilizing a modulation scheme in which a phase transition of a symbol waveform, which exerts an anti-multipath property by demodulating the signal on the receiving side, represents a waveform being changed, and then transmits the modulated signal at a transmission start timing. A predetermined delay amount is set such that 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 predetermined maximum number of effective branches for each symbol waveform, and such that each time difference between the reception timings is greater than or equal to a predetermined delay resolution and less than or equal to a predetermined maximum delay.
