Abstract: PROBLEM TO BE SOLVED: To suppress fading in a multiple path environment and to turn a defect of the presence of a reflection surface into an advantage, by using a 3rd polarization direction where a 3rd communication channel is generated effectively. SOLUTION: A third communication channel can be used for transmitting more information or transmitting the information having improved space diversity, so that the total communication performance is improved. The transmitting signal, having three polarization directions, is produced by a transmitter having three dipole antennas which are orthogonal to each other in a space, for example. The reception signal, having energy components in three polarization directions, is detected by a receiver having three dipole antennas orthogonal to each other in a space, for example.
