    • PURPOSE: A single tone control apparatus and method of a mobile communication system is provided to minimize a damage of a data by predicting the increase of a noise due to a single tone and heightening an IIP3 of a receiver, and reduce a power consumption by flowing the optimum current. CONSTITUTION: When a reception signal is inputted(701), an RSSI detector detects an RSSI and outputs it(703). And a signal-to-noise ratio detector receives the reception signal, detects an Eb/Nt of the reception signal and outputs it. The RSSI is inputted to a cross modulation signal strength detector, a TX AGC control signal generator and an RX AGC control signal generator, and the Eb/Nt is inputted to the cross modulation signal strength detector. When the RSSI and the Eb/Nt are detected, the cross modulation signal strength detector detects an IMDG signal and IMD signal strength and outputs them, and the TX AGC control signal generator and RX AGC control signal generator generate a TX gain control signal and a TX gain control signal and output them, respectively(705). When the TX gain control signal is generated, a Tx output signal is generated(709). When the Tx output signal is generated, a compensator detects the strength of the TX output signal, reads a compensation value for the cross modulation that can be reduced or increased by the TX output signal strength, and outputs it(711). Then, a coupler adds the compensation value and the signal outputted from the cross modulation signal strength detector and outputs it. The cross modulation control signal generator receives the signal outputted from the coupler, generates an IMD control signal for the signal, and outputs it to a transmission power amplifier or a drive amplifier(713).

    • PURPOSE: A device for generating a phase variable in a Gaussian minimum shift keying(GMSK) transmitter is provided to embody the GMSK transmitter which does not use a Gaussian low pass filter. CONSTITUTION: A device for generating a phase variable in a GMSK transmitter includes the following units. A plurality of operation blocks(100) consist of three multipliers for respectively multiplying three first input variables by three second input variables, and adders for adding values from the multipliers. A switching unit(130) connects an initial value in an initial stage, and connects a value obtained by adding an output value from a last delay to a third input variable, after the initial stage. A delay block(110) consists of an adder for adding an output value from the operation block(100) to a phase variable from the delay at the previous terminal, and a plurality of delays for delaying a value from the adder for a predetermined time. An output block(120) sequentially outputs a first phase variable from the switching unit(130) and phase variables from the plurality of delays of the delay block at predetermined intervals. As a result, a calculation amount is reduced and a circuit is simplified by calculating the phase variable with the plurality of multipliers, adders and delays.
