In this paper, wavelet packet transform (WPT) based de-noising receiver for visible-light communication (VLC) using a white light-emitting diode (LED) is studied for indoor applications such as short distance wireless connectivity, optical wireless local area network, and optical wireless input / output control devise (remote control). Previously, reported discrete wavelet transform based de-noising for indoor optical wireless communication; here we considered wavelet packet transform based de-noising technique. The process starts with the evaluation of the performance of de-noising receiver by calculating the received optical power, signal noise ratio (SNR), path loss and bit error rate (BER). Throughout the simulation results, the SNR performance is inversely proportional to the distance. Analytical study of SNR for VLC system without de-noising for indoor applications has been studied. In this paper de-noising technique is considered for reduction of noise. The DWPT based de-noising receiver, with a single source improves the SNR performance approximately by 2% compared to the one without de-noising receiver.

We firstly propose a hybrid-Radio-and-Visible-Light-Communication (HR-VLC) system in Inter-Vehicle Communication (IVC) employing Spread-Spectrum (SS) for better ranging and larger capacity. IVC, a key in Intelligent Transport System (ITS), is intended to improve the better safety and more convenient user experience. In the IVC, Radio communications system may not guarantee the precise ranging and large capacity. Thanks to the VLC with a good directionality and ubiquitous LEDs, a HR-VLC will support a reliable and better ranging system for IVC. Furthermore, the utilization of SS helps reduce the interference of ambient light proportionally to the processing gain. In the HR-VLC in IVC system, PPM is used as a modulation scheme due to high average power efficiency. It is verified that the proposed system achieves better BER performance and more precise ranging.
