<P>PROBLEM TO BE SOLVED: To provide an information transmission system for transmitting/receiving transmission signals of a plurality of channels while using one or a few antennas, respectively. Ž<P>SOLUTION: Transmitting-side virtual antennas 4a, 4b, ..., 4k are assumed at a transmitting-side signal preparing section 2 and receiving-side virtual antennas 13a, 13b, ..., 13k are assumed at a receiving-side signal detecting section, thereby providing a transmission single-antenna/reception single-antenna communication system wherein a transmitter 100 includes only one real antenna 7 and a receiver 200 includes only one real antenna 9. Thus, an information transmission system is configured which includes radio frequency utilization efficiency approximately equal to that of a transmission k-antenna/reception k-antenna communication system including k pieces of transmission antennas and k pieces of reception antennas.
