Performance comparison of two synchronization schemes for Colpitts circuits based chaotic communication system over noise channel
The synchronization performance of the Pecora-Carroll scheme and the error feedback scheme was investigated for two coupled chaotic Colpitts circuits. Both the mathematical derivation and numeric simulations indicate that the error feedback synchronization scheme outperforms the Pecora-Carroll synchronization scheme when the chaotic signal is transmitted over a noisy channel in which there exist an additive white Gaussian noise source and a channel filter. As a result, the information embedded in the chaotic signal, which passes a noisy channel from the transmitter to the receiver, can be recovered in a better way when the error feedback synchronization scheme is used.
