Patent ID: 7864833

Claim:
A method for measuring interference power in a time slot code division multiple access system, comprising: A. performing channel estimation for received signals with channel estimation codes, to obtain channel response results of all possible user terminals in the current cell, i.e., the original channel response estimation results h i , i=1 . . . P, wherein P is the total length of channel estimation windows; B. predetermining a threshold of number of taps W 1 , and selecting channel response estimation results corresponding to W 1 taps with less power from the original channel response estimation results h i according to the threshold of number of taps W 1 as a roughly estimated result of the interference power; and C. performing threshold processing on the original channel response estimation results with a signal-to-noise ratio threshold post-processing method by using the roughly estimated result of the interference power and a predetermined signal-to-noise ratio threshold, to obtain an accurate measured result of the interference power; wherein said threshold of number of taps W 1 is in a range of 50 to 90.
