Abstract:
    The related search method employs Teager-Kaiser energy operator to process the preliminary channel impulse response signal output by Steiner channel estimator and remove random distribution effect of path phase shift, then uses response signal to calculate power and estimate noise power for setting threshold, and extracting impulse response signal from every user window while setting inhibited noise into zero. This invention holds the effective multipath information, and removes pseudo path and noise.
