1. one-period enhancing equipment, be used to strengthen the periodic method of a pumping signal, the generation of this pumping signal is relevant with a new code vector with a tone code vector, think that synthetic broadband signal provides a signal composite filter, described periodicity enhancing equipment comprises:

  • A) factor generator is used to calculate the one-period sex factor relevant with described broadband signal;

    WithB) new wave filter is used for respect to this periodicity factor this new code vector being carried out filtering, reduces the energy of the low frequency component of this new code vector thus, and strengthens the periodicity of a low frequency component part of this pumping signal.
