Communication system based on chaotic delayed feedback oscillator with switched delay

We develop a secure communication system with chaotic switching. The proposed system is based on time-delayed feedback oscillator with switching of chaotic regimes. The proposed configuration of the receiver allows us to increase the scheme resistance to noise and amplitude distortions of the signal in a communication channel. The scheme is studied numerically and realized in a physical experiment. We illustrate the scheme efficiency for the transmission of binary information signal. The dependences of bit-error rate on the signal-to-noise ratio, signal attenuation in the communication channel, and duration of bit transmission are constructed.
