Abstract: PURPOSE: A frequency efficiency improving method in MC DS-CDMA(Multi-Carrier Direct Sequence Code Division Multiple Access) is provided to maintain target transmission quality by adaptively controlling transmission rates in a time domain. CONSTITUTION: Transmission power is allocated to a sub-channel including a maximum channel gain in MC DS-CDMA communication. Transmission rates are adaptively controlled in a time domain for maintaining transmission quality. A reception power gain is multiplied by the correlator output of an m channel in a coupling step of a reception signal. A beta value is used for a reception power gain value. A combiner of the user generates the amount of determination statistic.
