A study of signal detection method in power line communication based on Duffing chaotic system

In order to reduce SNR in power line communication and in combination with the excellent ability of Duffing chaotic system to detect weak signal, a method is proposed here by applying Duffing system to demodulate the power line communication signal. Simulation results show that, Duffing chaos receiving system can effectively demodulate power communication signal that is designed according to TWACS (Two Way Automatic Communication System). In addition, this system can well resist interference from other harmonic frequency signals.
