To provide a data transmission method including the symbol encoding step for producing a symbol to be transmitted via an communication channel established between a transmitter TR and a receiver REC.
The method according to the present invention further includes the symbol diffusing step. Within the symbol diffusing step, adjustable integer K number of serial symbols Z1, ..., ZK are to be diffused over some time duration chips before being transmitted. The adjustable number K is to be adjusted relating to physical characteristics of the communication channel CHNL. Consequently, data transmitted within an arbitrary given moment indicates what is mixed between K number of series symbols, not indicating a single symbol Zi in such a case as an already known MIMO system. Accordingly, a data diversity relating to a time to be detected at a reception end is introduced, and communication throughput between the transmitter TR and the receiver REC is adjusted.
