“…The key point is that considering the use of the same bandwidth enhance techniques for both pulse-based and efficient modulation schemes, the last ones achieve higher bit rates. The combination of efficient modulation schemes and different techniques for enhancing the available bandwidth can be found in [21]- [25] and [42]- [45].…”

Abstract-and Phase-Shift Keying (PSK). These modulation schemes achieve higher spectral efficiency (i.e., more data can be transmitted using the same bandwidth) than previously proposed modulation schemes performed by VLC transmitters based on the use of DC-DC power converters. To the author's knowledge, the ratio between the bit rate achieved and the switching frequency of the DC-DC power converter presented in this paper is the highest that can be found in literature.

“…This is particularly important to VLC as it has been shown that SNR in a VLC channel is typically in excess of 60 dB electrical, allowing the receiver to easily detect multiple amplitude levels in a signal [12]. For the same signal power and bit error rate, the work of [29] shows a data rate of 200 Mbps using unipolar OFDM while [30] achieved 125 Mbps using a binary signaling scheme; both techniques reported the use of blue light optical filtering at the receiver.…”

Color-shift keying (CSK) is a visible light communication (VLC) intensity modulation scheme, outlined in IEEE 802.15.7, that transmits data imperceptibly through the variation of the light color emitted by a red, green, and blue (RGB) light emitting diode (LED). Unlike other intensity modulation schemes, CSK guarantees that the intensity of the luminary will not fluctuate, thus limiting potential human health complications related to flickering light.In this work, a rigorous design framework for CSK constellations is presented. The benefits of the frame work are that it can optimize constellations while accounting for cross talk between the color communication channels formed by the colored LEDs.Unlike previous works, the method applies the study of colorimetry to optimize higher order CSK constellations such that the luminary functions with a desired operating color, allowing constellations to be designed to meet lighting industry quality metrics.

“…This modulation technique was able to achieve a transmission rate up to 200 Mbit∕s (Ref. 28) and currently improves the data transmission rate up to 513 Mb∕s. 13 In this analysis, the OOK modulation technique is used to provide the BW of the system up to 50 MHz for high data rate transmission.…”

Optimization of signal-to-noise ratio for wireless light-emitting diode communication in modern lighting layouts

Abstract. White light-emitting diodes (LEDs) are predicted to be widely used in domestic applications in the future, because they are becoming widespread in commercial lighting applications. The ability of LEDs to be modulated at high speeds offers the possibility of using them as sources for communication instead of illumination. The growing interest in using these devices for both illumination and communication requires attention to combine this technology with modern lighting layouts. A dual-function system is applied to three models of modern lighting layouts: the hybrid corner lighting layout (HCLL), the hybrid wall lighting layout (HWLL), and the hybrid edge lighting layout (HELL). Based on the analysis, the relationship between the space adversity and the signal-to-noise ratio (SNR) performance is demonstrated for each model. The key factor that affects the SNR performance of visible light communication is the reliance on the design parameter that is related to the number and position of LED lights. The model of HWLL is chosen as the best layout, since 61% of the office area is considered as an excellent communication area and the difference between the area classification, Δp, is 22%. Thus, this system is applicable to modern lighting layouts. © The Authors. Published by SPIE under a Creative Commons Attribution 3.0 Unported License.
