摘要： 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 the reception device receives the plurality of pseudo propagation path characteristic information transmitted antecedently from the transmission device and a communication signal transmitted subsequently, and individually extracts the plurality of data from the communication signal based on the plurality of pseudo propagation path characteristic information.
