Superposed pulse amplitude modulation for visible light communication.
We propose and experimentally demonstrate a novel modulation scheme called superposed pulse amplitude modulation (SPAM) which is low-cost, insensitive to non-linearity of light emitting diode (LED). Multiple optical pulses transmit parallelly from different spatial position in the LED array and overlap linearly in free space to realize SPAM. With LED arrangement, the experimental results show t...
متن کاملDual Amplitude-Width Pulse Interval Modulation for Optical Wireless Communications
In this paper, a new modified digital pulse interval modulation called Dual Amplitude-Width Pulse Interval Modulation (DAWPIM) is presented, on the basis of Pulse Amplitude Modulation (PAM) and Pulse Width Modulation (PWM), and its properties are presented. After introducing symbol structure, data rate improvement, average normalized power requirement and bandwidth efficiency are studied. The p...
متن کاملDifferential Amplitude Pulse-Position Modulation for Indoor Wireless Optical Communications
We propose a novel differential amplitude pulse-position modulation (DAPPM) for indoor optical wireless communications. DAPPM yields advantages over PPM, DPPM, and DH-PIMα in terms of bandwidth requirements, capacity, and peak-to-average power ratio (PAPR). The performance of a DAPPM system with an unequalized receiver is examined over nondispersive and dispersive channels. DAPPM can provide be...
متن کاملA Carrierless Amplitude Phase (CAP) Modulation Format: Perspective and Prospect in Optical Transmission System
Received Dec 14, 2016 Revised Apr 15, 2017 Accepted Apr 30, 2017 The explosive demand of broadband services nowadays requires data communication systems to have intensive capacity which subsequently increases the need for higher data rate as well. Although implementation of multiple wavelengths channels can be used (e.g. 4 × 25.8 Gb/s for 100 Gb/s connection) for such desired system, it usually...
متن کاملCoded Modulation with APSK for OFDM-Based Visible Light Communications
Coded modulation with APSK is proposed for OFDM-based VLC systems. Simulation results show that the proposed scheme achieves better performance than conventional QAM counterpart in both DCO-OFDM and ACO-OFDM systems, while similar complexity is maintained. OCIS codes: (060.2605) Free-space optical communication; (060.4080) Modulation.
