Visible Light Communication System Using an Organic Bulk Heterojunction Photodetector
A visible light communication (VLC) system using an organic bulk heterojunction photodetector (OPD) is presented. The system has been successfully proven indoors with an audio signal. The emitter consists of three commercial high-power white LEDs connected in parallel. The receiver is based on an organic photodetector having as active layer a blend of poly(3-hexylthiophene) (P3HT) and phenyl C6...
متن کاملA Chaos-based Spread Spectrum Communication System
We describe the design and CMOS implementation of a baseband spread-spectrum communication system using chaotic signals for spreading digital data. The communication system uses a new chaotic modulation scheme called M-DCSK (Modified Differential Chaos Shift Keying). The M-DCSK scheme and its characteristics are analyzed for single user and multi user applications. Results from a VLSI implement...
متن کاملTechniques of Spectrum and Correlation Characteristics for Ultrasonic Ranging System
Both the spectrum and correlation characteristics are important in constructing excitation sequences to realize the multichannel ultrasonic sensors working together. For LFM excitation sequence, there should not be too many simultaneously fired ultrasonic sensors, because of the limited available frequency band of the ultrasonic ranging system. The optimized CFM excitation sequences are propose...
متن کاملUltrasonic Multiple-Access Ranging System Using Spread Spectrum and MEMS Technology for Indoor Localization
Indoor localization of persons and objects poses a great engineering challenge. Previously developed localization systems demonstrate the use of wideband techniques in ultrasound ranging systems. Direct sequence and frequency hopping spread spectrum ultrasound signals have been proven to achieve a high level of accuracy. A novel ranging method using the frequency hopping spread spectrum with fi...
متن کاملSpread Spectrum using Chaotic System
Chaotic signal helps in a secure communication, by generating wideband spectra of random sequences. Chaotic signal has the property of synchronization; data are transmitted from one location to another by mapping bit sequences to symbols, and symbols to sample functions of analog waveforms. The synchronization between two digital chaotic oscillators, serving as a transmitterreceiver scheme, is ...
