METHOD OF COMBINING A PLURALITY OF TRANSMISSION DATA BY OFDM MODULATION, AND SYSTEM FOR TRANSMITTING A PLURALITY OF DATA BY OFDM MODULATION

摘要

PROBLEM TO BE SOLVED: To provide a method of combining a plurality of transmission data and system for transmiting a plurality of data by OFDM modulation which enables combination (addition) of data as in the form of modulated signals using the orthogonality of a plurality of carrier signals in OFDM modulation wherein orthogonal carrier signals are modulated by the transmission data, to be converted into modulated signals. SOLUTION: Out of the carrier signals to be subjected to OFDM modulation, odd-numbered carrier signals are modulated by the transmission data A, while even-numbered carrier signals are modulated by the transmission data B. Modulated signals of the odd-numbered carrier signals modulated by the data A and those of the even-numbered carrier signals modulated by the data B are combined as in the form of the modulated signals.
