Power line communication de-noising based on chaotic parameter modulation and wavelet transform

As a medium of signal transmission, communication using power line offers a convenient and inexpensive solution for multimedia signal transmission and control applications. This paper aims to present a de-noising scheme which is a combination between chaotic parameter modulation and wavelet transform in power line communications (PLC). The proposed communication scheme is based on two key ideas. The first concept consists of the use of the parameter modulation based on chaotic sequence in order to minimize interference caused by the power line and to secure the transmission information. The second idea consists of the use of wavelet transform based on modulus maxima to reduce the noise from a chaotic sequence. Performance analyses such as signal-to-noise (SNR), root mean squared error (RMSE) and bit error rate (BER) illustrate the superior communication performance of the proposed PLC de-noising scheme based on chaotic parameter modulation and wavelet transform.
