1. a finger front end of processing multiple channels, is characterized in that comprising:

  • Shift register, for receiving I and Q sampling and it being shifted, wherein multiple I and Q sampling can be accessed in a parallel manner;

    Parallel and calculator, samples and generates I and Q result for receiving multiple I and Q;

    Accumulator, for each movable channel is added up I and Q result in a part is cumulative, and cumulative according to the spreading factor relevant to movable channel output in code element boundary conditionally;

    Scheduling device, thereby for controlling described shift register and described parallel and calculator to make described shift register and described parallel and computer time share each the generation result for multiple channels, and for driving described accumulator to export,Wherein said parallel and calculator also comprises the Solution Expander for described multiple I and Q result being carried out with multiple I and Q PN sequential value de-spread.
