MULTI-CARRIER CDMA COMMUNICATION DEVICE, MULTI-CARRIER CDMA TRANSMITTING DEVICE, AND MULTI-CARRIER CDMA RECEIVING DEVICE |
摘要 |
On the transmission side provided are a data modulation control section (4) for setting a predetermined parameter required for demodulation, subcarrier group modulating sections (6a to 8c) for performing frequency-spreading in units of a subcarrier signal of subcarriers according to the setting, and time-spreading sections (10a to 10c) for multiplexing all the signals after the modulation and frequency spreading in units of a subcarrier signal so as to time-spread the multiplexed signal. On the reception side provided are time-despreading sections (35a to 35c) for performing time-despreading in units of a subcarrier signal and subcarrier group demodulating sections (36a to 38c) for performing frequency-despreading in units of a subcarrier signal time-despread.
