  • INTERFERENCE LEVEL ESTIMATION OF PATH MONITORING IN W-CDMA USING THE ORDER STATISTICS OF BEAULIEU SERIES
    Publication number: 20090060105
    Abstract: A technique for interference level estimation for a WCDMA system based on the low order statistics of Beaulieu Series is provided. Correlation of a locally generated copy of a dedicated physical control channel (DPCCH) with the input samples of the radio frequency message is performed using low order statistics of a Beaulieu Series to estimate an interference level and thereby implicitly separate a set of multipath components from a noise floor.

  • Beaulieu series approach to optimal UMTS RACH preamble detection estimation
    Patent number: 7394875
    Abstract: A method for preamble detection in mobile unit to base unit wireless telephony sets a preamble detection threshold based upon a Beaulieu series computation dependent upon preamble correlation data. This preamble detection threshold adjusts for noise by assuming the noise is additive White Gaussian noise (AWGN) with a known variance. The method determines the threshold for achieving a probability of false detection of the preamble from noise input of less than 0.001.
