Abstract
The multicarrier transfer system employing the OFDM/CDMA modulation system comprises a transmitter having an S/P converter which two-dimensionally arranges spread signals for a transmission data array on a frequency and time axes system and then rearrange the spread signals for one transmission data array arranged two-dimensionally. The transmitter transmits the signals generated in the S/P converter. A receiver receives the signals transmitted by the transmitter and demodulates the signal to reconstruct the transmission data array.
