Space-division multiplex communication method of executing multiplex communication |
摘要 |
In a space-division multiplex communication method of executing multiplex communication according to this invention, a plurality of radio beams a-a' to d-d' radiated at same frequency in different directions and rotated at same rotational angular speed omega are independently received in synchronism with the rotational angular speed omega by a plurality of communication terminals R1 to R3 arranged at arbitrary positions in a space where the radio beams can be received, thereby realizing unidirectional multiplex communication using the same frequency. Interstation bidirectional multiplex communication is performed by introducing a frequency-division system to the communication terminals R1 to R3 of the unidirectional multiplex communication. The space-division multiplex communication method can effectively use a frequency by a multiplex communication system of space-dividing a radio beam.
