1. , a kind of method of extracting multipath is characterized in that comprising step:

  • Every road signal energy data flow of antenna reception is delivered to the shift register of certain-length;

    After described shift register moves into new data at every turn, judge whether the data of fixed position in this register are not less than the data of all the other positions, if then the data of this position are preserved as energy peak, and with the data zero clearing of described all the other positions;

    Energy peak is carried out the multi-path threshold judgement, will export as the multipath data above the energy peak of multi-path threshold.
