Abstract:
A radio communication method of exchanging a transmission signal, which has been modulated by a prescribed method based on information data, between plural communication terminals and controlling said plural communication terminals by a control terminal, the radio communication method comprising the steps of:causing said control terminal to generate a first code sequence to synchronize with said plural communication terminals and transmitting the first code sequence to said plural communication terminals; synchronizing said communication terminal with said control terminal based on a reference timing obtained by receiving said first code sequence, generating a second code sequence representing the demodulation timing for said transmission signal and transmitting the second code sequence to another communication terminal out of said plural communication terminals, and then transmitting said transmission signal to said other communication terminal after transmitting said second code sequence; and causing said other communication terminal to demodulate said transmission signal, received following said second code sequence, based on said demodulation timing obtained by receiving said second code sequence.
