Abstract

In multiuser impulse radio systems, the conventional detection methods always suffer from high complexity and poor robustness caused by dense multipath and long maximum excess delay of the nonline-of-sight (NLOS) channel. To detect the direct spread (DS) impulse signal, an adaptive pre-interpolation filter algorithm is introduced. By analysis and simulation, this adaptive interpolator applied before the decorrelator is proved to have a good steady-state performance of the adaptation.
