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.

Abstract: PURPOSE: A method for determining a position of a movable body of a navigation system is provided to calculate a driving distance of the movable body per unit hour by setting a driving distance conversion factor according to a driving speed of the movable body, thereby enabling to reduce errors. CONSTITUTION: A method for determining a position of a movable body of a navigation system is as follows. The reliability of position information received from a GPS(Global Positioning System) satellite when driving the movable body is determined(S200,S201). When the reliability of the position information is higher than a preset standard, a position of the movable body is determined by reflecting the position information to a position determination algorithm(S202). The determined position information of the movable body is displayed on a digital map by map-matching(S203). When the reliability of the position information is lower than the preset standard, whether or not a driving speed of the movable is higher than a preset speed is determined based on the number of pulse signals per unit hour generated by a speedometer by driving the movable body(S204,S205). When the driving speed of the movable body is higher than the preset speed, a driving distance per unit hour of the movable body is calculated by setting a driving distance conversion factor based on the number of the pulse signals(S206,S208).
