1. a downstream signal processing unit is applied to the base station down link, it is characterized in that, said downstream signal processing unit comprises:

  • Downstream signal discrimination unit, public baseband processing unit and professional baseband processing unit;

    Wherein,Said downstream signal discrimination unit links to each other with transmission unit in the said base station, is used to receive the downstream signal that said transmission unit sends, and distinguishes the type of said downstream signal, and said downstream signal is divided into common downlink signal and professional downstream signal;

    Said public baseband processing unit links to each other with said downstream signal discrimination unit;

    Be used to receive said downstream signal discrimination unit and distinguish the common downlink signal that obtains;

    Said common downlink signal encoding and modulation are obtained public baseband signal, and said public baseband signal is sent to the carrier frequency unit;

    Said professional baseband processing unit links to each other with said downstream signal discrimination unit;

    Be used to receive said downstream signal discrimination unit and distinguish the professional downstream signal that obtains;

    Said professional downstream signal coding and modulation are obtained professional baseband signal, and said professional baseband signal is sent to the carrier frequency unit.
