摘要： A method is provided for transmitting a signal in a signal transmission apparatus of a communication system. Upon receiving a signal, the signal transmission apparatus determines a mode of the received signal, in which a power amplifier should amplify the signal; generates a mode control signal corresponding to a single mode, if the mode of the received signal is determined as the single mode; amplifies and transmits the received signal in the single mode according to the mode control signal; generates a mode control signal corresponding to a multi-mode, if the mode of the received signal is the multi-mode; and amplifies and transmits the received signal in the multi-mode according to the mode control signal.

摘要： An apparatus and method for controlling a digital AGC in a communication system in which power changes significantly from frame to frame. In the digital AGC controlling apparatus, an SNR estimator estimates an uplink SNR of a next frame. A power measurer measures uplink received power of every frame. A gain calculator estimates uplink power of an nth frame using an SNR estimate of an (n−1)th frame received from the SNR estimator and a received power measurement of the (n−1)th frame received from the power measurer, and calculates a gain to be applied to the nth frame in the digital AGC using the uplink power estimate of the nth frame.

摘要： A base station power amplifier for minimizing memory effect is provided. The power amplifier includes a bias circuit which supplies a direct current (DC) power to a transistor; the transistor which amplifies the DC power provided from the bias circuit; a matching circuit which transfers maximum power to a load by reducing loss of the power amplified by the transistor; and a large capacitor which lies between the matching circuit and the transistor, reduces a low-frequency second harmonic voltage by electrically connecting directly to the matching circuit, and has a preset capacitance value.
