1. finger front end of handling a plurality of channels is characterized in that comprising:

  • Shift register is used to receive I and Q sampling and to its displacement, wherein a plurality of I and Q sampling can be visited in a parallel manner;

    Parallel and calculator is used to receive a plurality of I and Q sampling and generates I and Q result;

    Accumulator is used for each active channels is added up I and Q result in a part adds up, and adds up according to spreading factor output on the code element boundary relevant with active channels conditionally;

    The scheduling device is used to control shift register, parallel and calculator and accumulator, thereby makes their time share each the generation code element for a plurality of channels;

    Sampling processor is used for generating a plurality of processed samplings from a plurality of samplings with the parallel mode visit, and described sampling processor comprises a Solution Expander that the sampling of being visited is carried out de-spread with the fragment of extended code.
