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.
