Abstract: An apparatus for power transmission in a wireless communication system is provided to lower the impedance of bias voltage and minimize the memory effect of an EER(Envelope Elimination and Restoration) power transmitter by improving the efficiency and linearity of a bias modulator which provides the bias voltage of the EER power transmitter. An EER power transmitter in a wireless communication system comprises a DSP(Digital Signal Processor)(200), a bias modulator(210), a frequency modulator(220), and a power amplifier(240). The DSP separates a signal to transmit into a size component and a phase component and outputs them. The bias modulator amplifies the size component, lowers the impedance, and outputs it. The frequency modulator modulates the phase component into an RF(Radio Frequency) signal. Using the size component outputted from the bias modulator as bias voltage, the power amplifier amplifies the RF signal.

Abstract: A downlink voice packet network packet scheduling device in a mobile communication base station system and a method thereof are provided to measure delay time when delay is started if the transmission delay of VoIP(Voice over Internet Protocol) packets occurs, and to previously set packet loss in a suitable ratio, thereby reducing the transmission delay of the VoIP packets. When packets of a voice packet network are received, network transmission delay time is calculated by using a difference of time stamp values in case of base station arrival time and generation of the packets(301-305). If the packets refer to packets to be currently scheduled, queuing delay time is calculated by using a difference between base station departure time and the base station arrival time of the packets(307-313). Packet transmission delay time is calculated by using a sum of the queuing delay time and the calculated network transmission delay time(315). It is checked whether the calculated packet transmission delay time satisfies a predetermined threshold value, and if so, transmission of the packets is determined, and if not, dropping of the packets is determined(317-323,325).
