A Noise Eliminating Method of DCSK System Based on Multi-Layered Noise Control Materials

Abstract:

This paper proposes a new chaotic communication scheme which is developed from Differential Chaos Shift Keying (DCSK), named reversed-phase overlay DCSK. Different from DCSK, at the receiver of the improved scheme the first and the second half-symbol signals within a code period are reversed-phase overlapped before the correlation operation. Both the theoretical analysis and the simulation results show that the proposed scheme can effectively suppress the noise and improve the BER performance of DCSK if the channel noise in the first half of a code period and the second is positively correlated. The proposed scheme can be applied to the communication systems suffering with colored noise, such as Low-voltage Power Line Communication(L-PLC) system
