Claim Text:
1. A transmitting/receiving method, wherein a transmitting side has a plurality of virtual transmission antennas and one or a plurality of actual transmission antennas, the number of the actual transmission antenna is at least less than that of the virtual transmission antenna, a receiving side has one or a plurality of actual reception antennas and a plurality of virtual reception antennas, the number of the actual reception antenna is at least less than that of the virtual reception antenna, a virtual channel exists between respective transmitting side virtual transmission antennas and the actual transmission antenna, and a virtual reception channel exists between the actual reception antenna and respective receiving side virtual reception antennas, the method comprising operations in which: separate data signals are input to respective virtual transmission antennas of the transmitting side, separate time characteristics, which correspond to separate virtual channels for the respective virtual transmission antennas, are convoluted with respective ones of the separate data signals input to the respective virtual transmission antennas to pass the separate data signals through the separate virtual channels, an addition is performed on an output of each of the virtual channels and the result is transmitted from the actual transmission antenna, and on the receiving side, a first signal received by the actual reception antenna is branched, the time characteristics of separate virtual reception channels are convoluted and are input to the virtual reception antennas corresponding to respective virtual reception channels, and the virtual reception antennas output a second signal.
