Abstract
By performing orthogonal frequency division multiplexing on the transmission signal to form an OFDM modulated signal (indicated in the figure), the OFDM signal is subjected to orthogonal frequency division multiplexing and code division multiple access processing on the transmission signal. By forming a CDM modulated signal (indicated by diagonal lines in the figure) and transmitting an OFDM modulated signal and an OFDM-CDM modulated signal, data can be transmitted at a very high rate by the OFDM modulated signal and at the same time, OFDM- The CDM modulated signal makes it possible to transmit data with a higher quality than the OFDM modulated signal although it is slightly behind the OFDM modulation in terms of high speed transmission.
