    摘要： When reception quality of signals detected by a reception Eb/Io (ratio of power received waves to power of interfering waves) detector is equal to or more than a predetermined value and a frame error rate (FER) set by an FER measuring section for a first reference level or more is less than a predetermined reference value, a target Eb/Io setting section sets a value to increase the target reception quality. When the reception quality of signals thus detected is less than the predetermined value and the frame error rate set by the FER measuring section is equal to or more than the predetermined reference value, the target Eb/Io setting section sets a value to decrease the target reception quality.

    摘要： A modulation system responsive to a sampled signal (31) of a sampling rate for supplying a modulated analog signal to an amplifier having nonlinearities to make the amplifier produce an amplified output signal, in which a processing arrangement (36) processes the signal with reference to a difference between the signal and an additional digital signal (35) to compensate for the nonlinearities to produce a processed signal. The processed signal is modulated into the modulated analog signal. The amplified output signal is demodulated and converted into the additional digital signal by a converter (40). Otherwise, the second control signal is produced. A controller (78) may control a phase of a sampling signal supplied to the converter so that a quotient of the difference by a differential of the selected signal becomes equal to zero.
