Phototransistor-like Light Controllable IoT Sensor based on Series-connected RGB LEDs
Shangbin Li, Shuang Liang, Zhengyuan Xu
An IoT optical sensor based on the series-connected RGB LEDs is designed, which exhibits the light-controllable optical-to-electrical response like a phototransistor. The IoT senso…
Pulse-laser Based Long-range Non-line-of-sight Ultraviolet Communication with Pulse Response Position Estimation
Ruixiong Xu, Chen Gong, Zhengyuan Xu
We propose pulse laser-based ultra-violet communication over long distance, such that the pulse response signals can be detected at the receiver at the cost of low data transmissio…
Sunlight Enabled Vehicle Detection by LED Street Lights
Weicheng Xue, Shangbin Li, Zhengyuan Xu
We propose and demonstrate a preliminary traffic sensing system based on the widely distributed LED street lights. The system utilizes and discriminates the photoelectric responses…
Clipping noise approximate analysis and power allocation for photon-detection-based DCO-OFDM and ACO-OFDM
Zhimeng Jiang, Chen Gong, Zhengyuan Xu
The clipping noise of the photon-level detector for both direct current-biased optical OFDM (DCO-OFDM) and asymmetrically clipped optical OFDM (ACO-OFDM) is investigated. Based on…
Constrained Partial Group Decoding with Max-Min Fairness for Multi-color Multi-user Visible Light Communication
Guangtao Zheng, Chen Gong, Zhengyuan Xu
A visible light communication (VLC) system can adopt multi-color light emitting diode (LED) arrays to support multiple users. In this paper, a multi-layer coding and constrained pa…
Asynchronous Multiple Access in Optical Wireless Scattering Communication: Achievable Transmission Rates and Receiver Design
Guanchu Wang, Chen Gong, Zhimeng Jiang +1
We investigate the asynchronous multiple user access communication in optical wireless scattering communication, where different users transmit signals without perfect alignment in…
Statistical Non-linear Model, Achievable Rates and Signal Detection for Photon-level Photomultiplier Receiver
Zhimeng Jiang, Chen Gong, Zhengyuan Xu
We characterize the practical receiver in a wide range of signal intensity for optical wireless communication, from discrete pulse regime to continuous waveform regime. We first pr…
A 1Mbps Real-time NLOS UV Scattering Communication System with Receiver Diversity over 1km
Guanchu Wang, Kun Wang, Chen Gong +3
In the non-line of sight (NLOS) ultraviolet (UV) scattering communication, the received signals exhibit the characteristics of discrete photoelectrons due to the extremely large pa…
