【Abstract】 Taking the advantage that the local linear projective algorithm (LLPA) does not have to know the dynamics of chaotic signals in advance, it uses this algorithm in the receiver end of Chaotic Shift Keying (CSK) system for the noise reduction. This method proves to be of high efficiency on improving the noise performance of the CSK system via computer simulations, accordingly confirms the validity of LLPA algorithm and widens the application fields in the noise reduction of chaotic communications systems.更多还原
