  • Abstract
    Prediction error filter (PEF) design for narrowband interference (NBI) excision is examined for a hopped direct-sequence spread-spectrum system. The PEF is obtained by application of the Levinson Durbin algorithm (LDA). Several enhancements are utilized: unbiased autocorrelation estimation and normalization. LDA modification, and PEF weight normalization. The resulting composite technique provides a high-performance excision algorithm
