An improved QRD-LSL interpolation algorithm based on QR-Decomposition is proposed for Narrow-Band-Interference (NBI) suppression in DSSS. Impacts of interior properties of QRD-LSL interpolators on the performance of NBI suppression are analyzed in detail. The interior properties of QRD-LSL interpolators include combination property and symmetry property. The theoretic analyses and experiment data have proved that the order of stage recursion is the feeblish impact on the performance of NBI suppression and the symmetrical QRD-LSL interpolators have the optimization framework to NBI suppression.
