1. An apparatus for processing a downlink signal, applied to a downlink of a base station, the apparatus comprising:

  • a computer including a non-transitory computer-readable medium storing program units executable by the computer, the units including;

    a baseband signal differentiating unit;

    a public carrier module; and

    a traffic carrier module;

    a public power amplifier unit; and

    a traffic power amplifier unit;

    wherein the baseband signal differentiating unit is configured to be connected to a baseband processing unit of the downlink of the base station, to receive a baseband signal transmitted by baseband processing unit, and to differentiate a type of the received baseband signal, wherein the baseband signal is classified into a public baseband signal and a traffic baseband signal;

    wherein the baseband signal differentiating unit differentiates the type of the baseband signal by determining the type of the baseband signal and wherein the baseband signal differentiating units sends, according to the determined type of the baseband signal, the received baseband signal to only one of the public carrier module or the traffic carrier module;

    wherein the public carrier module is connected to the baseband signal differentiating unit and is configured to receive a public baseband signal obtained by the baseband signal differentiating unit by the differentiating, to perform up-conversion and digital-to-analog conversion on the public baseband signal to obtain a public carrier signal, and to transmit the public carrier signal to the public power amplifier unit;

    wherein the traffic carrier module is connected to the baseband signal differentiating unit and is configured to receive a traffic baseband signal obtained by the baseband signal differentiating unit by the differentiating, to perform up-conversion and digital-to-analog conversion on the traffic baseband signal to obtain a traffic carrier signal, and to transmit the traffic carrier signal to the traffic power amplifier unit;

    wherein the public power amplifier unit is connected to the public carrier module and is configured to receive the public carrier signal transmitted by the public carrier module and to output a public output signal after amplifying power of the public carrier signal; and

    wherein the traffic power amplifier unit is connected to the traffic carrier module and is configured to receive the traffic carrier signal transmitted by the traffic carrier module and to output a traffic output signal after amplifying power of the traffic carrier signal.
