Title: Mobile communication system with offset compensation circuitry

Abstract: A mobile communication system comprising an analog baseband processor thatis configured for providing improved DC offset compensation. An offsetcompensation circuit of the analog baseband processor generates a first DCoffset compensation signal to preset DC offset voltage of analog basebandsignal when the mobile communication system is power on. A mobile stationmodem of the mobile communication system generates a second DC offsetcompensation signal to compensate for a detected DC offset voltage duringoperation of the mobile communication system subsequent to the DC offsetvoltage being preset. In addition, the offset compensation circuitre-presets the DC offset by generating a third DC offset compensationsignal whenever the mobile communication system enters a predeterminedmode of operation such as a "data send" mode.
