1. a kind of propagation path system of selection in band spread receiver may further comprise the steps:

  • Estimate the signal to noise ratio relevant with the complex signal that receives;

    Calculated threshold coefficient on the basis of this signal to noise ratio;

    A noise level relevant with this signal to noise ratio with described threshold value multiplication, obtained a path selection threshold;

    Described propagation path characteristic and described path selection threshold are compared;

    WithWhen described characteristic surpasses described path selection threshold, select described propagation path.
