Abstract: PURPOSE: A method for attenuating an intermodulation in a receiver of a mobile communication system is provided to attenuate a leaked transmitting power by a low noise amplifier of the receiver, so as to improve a linearity of the low noise amplifier and reception characters, and to save a power consumed while keeping the linearity of the low noise amplifier to reduce a using time of a terminal. CONSTITUTION: A modem checks whether a signal received from a baseband analog is inputted(501). If so, the modem decides a transmission power according to the received signal(503). If the transmission power is decided, the modem compares the transmission power with a transmission power level stored in a memory of the modem(505). If the transmission power is larger than the transmission power level, the modem outputs a control signal for attenuating the transmission power to an attenuator(507).

Abstract: PURPOSE: A structure of a synchronous wide band CDMA for wireless packet communication is provided to be applicable to packet communication as well as circuit communication with improving demodulation efficiency of a receiver. CONSTITUTION: An IF band pass filter(102) filters only wide band including information in the output signals of a mixer(101). A QPSK demodulator(103) receives the signal outputted from the IF band pass filter(102) for generating carrier wave signal having same phase and orthogonal phase on the basis of the first IF clock signal generated in a PLL block(105), and separates I channel and Q channel by using the carrier wave signal. An A/D converter(104) converts an analog base band signal into a digital sample. The PLL block(105) generates a master clock which becomes a clock source for operation of a modem. A TCXO(Temperature Controlled Crystal Oscillator)(106) supplies a reference clock to the PLL block(105) and varies the reference clock according to the output value of a low pass filter(107). A match filter block(108) receives a digital sample and calculates an energy by chip units, and compares the calculated energy with an inner set energy. A synchronous code tracking block(109) receives a digital sample, detects a timing error by chip unit, and controls timing by sub-chip units for meeting code synchronization and generating a PN chip clock. A channel phase and frequency error tracking block(110) separates only a pilot signal from the received signal and calculates amplitude and composition of the channel. A synchronous demodulating block(11) demodulates the QPSK modulated signal by traffic channels for restoring a symbol.
