  • Transmission/reception method and transmission/reception system
    Patent number: 11271789
    Abstract: The present invention is a transmission/reception method in which a reception device measures propagation path characteristics of a communication propagation path, a transmission device generates, based on a measurement result of the propagation path characteristics, a plurality of pseudo propagation path characteristics having propagation path characteristics similar to the propagation path characteristics so as to have low mutual correlation, the transmission device generates a data group including a plurality of parallel and independent data in the same number as the plurality of pseudo propagation path characteristics in a baseband on a transmitting side, obtains a transmission signal by synthesizing a plurality of superimposed data generated by superimposing the pseudo propagation path characteristics on the data one by one, and transmits a plurality of pseudo propagation path characteristic information relating to the plurality of pseudo propagation path characteristics and the transmission signal, and
