Subspace based PN code sequence estimation for directsequence signals using a simplified Hebb rule
Faith Dominique, John H. Chip Reed · Electronics Letters · 1997
It is known that a tapped delay line FIR filter adapted by the constrained Hebbian rule can blindly estimate the code sequence of a direct sequence (DS) signal, provided that the estimation is symbol synchronous. A modification is proposed to the existing Hebb based blind sequence estimator to reduce the number of computations required; simulation results are presented.
