Title:
METHOD, DEVICE, AND SYSTEM FOR COMMUNICATION UTILIZING CARRIER METHOD BY MUTUALLY INDEPENDENT POLARIZED PLANES
Document Type and Number:
Japanese Patent JP3870170
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a radio communication method for extending a digital transmission band by utilizing two different polarized planes and performing amplitude shift modulation by comparison of relative amplitudes in respective polarized planes and superposing it over the existing phase shift modulation.
SOLUTION: The radio communication method comprises; a step of generating codes associated with relative values of amplitude strength of a first polarized wave to be transmitted and a second polarized wave independent of the first polarized wave, correspondingly to transmission data; a step of modulating the first and second polarized waves correspondingly to the codes and transmitting them; a step of receiving the transmitted first and second polarized waves and detecting amplitude strength of the first and second polarized waves; a step of decoding the codes from the detected amplitude strength; a step of reproducing the transmission data from the decoded codes.
