  • Method and apparatus for robust acquisition of spread spectrum signals
    Patent number: 7292624
    Abstract: A Direct Sequence Spread Spectrum receiver is described in which a complex spread spectrum signal is cross correlated by four digitally matched filters. The filters and subsequent multipliers correlate the in-phase and quadrature components as well as the current and previous symbols. The result is a more robust signal acquisition at very low signal to noise ratios.
    Type: Grant
    Filed: August 27, 2002
    Date of Patent: November 6, 2007
    Assignee: ITT Manufacturing, Inc.
    Inventors: Michael A. Mayor, Lester G. Matheson, Robert D. Martin, John H. Gass, Mhairi N. McCune
