1. , for a power detecting method, comprising:

  • The first and second algorithms are used to determine the power be associated with baseband signal;

    The power calculated at use first algorithm is more than producing high power indicator during the first thresholding and once the gain state producing described high power indicator and determine whether to change Wireless Telecom Equipment;

    AndThe power calculated at use second algorithm produces low power indicator more than during the second thresholding,Wherein said first algorithm is by calculating power to the in-phase component of the sampling of described baseband signal and the amplitude of quadrature component with quadraturing, and described second algorithm is quadratured by the in-phase component of the sampling to described baseband signal and the quadratic sum of quadrature component and calculated power, described first algorithm calculates power quickly than described second algorithm.
