Mobile communication system with offset compensation circuitry |
摘要 |
A mobile communication system comprising an analog baseband processor that is configured for providing improved DC offset compensation. An offset compensation circuit of the analog baseband processor generates a first DC offset compensation signal to preset DC offset voltage of analog baseband signal when the mobile communication system is power on. A mobile station modem of the mobile communication system generates a second DC offset compensation signal to compensate for a detected DC offset voltage during operation of the mobile communication system subsequent to the DC offset voltage being preset. In addition, the offset compensation circuit re-presets the DC offset by generating a third DC offset compensation signal whenever the mobile communication system enters a predetermined mode of operation such as a "data send" mode.
