“…Despite myriad reports of effective equalisation methods in the literature (i.e. [18]), we elected not to extend the bandwidth of the proposed system as we do not consider the impact of band-limitations in this work and as such, the overall data rate is not the focus of this work and can be set arbitrarily. Hence, we set the signal bandwidth to 1 MHz in order to ensure operation within the pseudoflat portion of the system magnitude response and enable demodulation via a low-pass filter (LPF), in a similar manner to our previous work [13].…”

Abstract-This paper proposes and experimentally demonstrates, for the first time, two new candidate pulse shapes for carrier-less amplitude and phase modulation in the context of visible light communications. It is commonly accepted that the pulse shape at the heart of the Hilbert pair used to generate the required orthogonal signal spaces should be the square-root raised cosine. In this work, we introduce two additional candidate pulse shapes, namely the first-order Xia pulse and the socalled better-than-Nyquist pulse. We demonstrate experimentally that the better-than-Nyquist pulse offers superior bit-error rate performance compared to the square-root raised cosine and Xia pulses under additive white Gaussian noise channel conditions, whilst offering lower computational complexity.

“…Even with such a slow response rate, the modulation frequency in VLC based on commercial WLEDs has been pushed to hundreds of MHz, by resorting to regions of small signals, using advanced detection and signal equalizing circuits. The transmission rate can be further boosted to over Gbit speeds by using spectrally efficient modulation techniques . We envision that if we can improve the intrinsic physical response frequencies of WLEDs, we will be able to further increase the capability of the VLC technology.…”

A metal-organic layer (MOL) is a new type of 2D material that is derived from metal-organic frameworks (MOFs) by reducing one dimension to a single layer or a few layers. Tetraphenylethylene-based tetracarboxylate ligands (TCBPE), with aggregation-induced emission properties, were assembled into the first luminescent MOL by linking with Zr O (OH) (H O) (HCO ) clusters. The emissive MOL can replace the lanthanide phosphors in white light emitting diodes (WLEDs) with remarkable processability, color rendering, and brightness. Importantly, the MOL-WLED exhibited a physical switching speed three times that of commercial WLEDs, which is crucial for visible-light communication (VLC), an alternative wireless communication technology to Wi-Fi and Bluetooth, by using room lighting to carry transmitted signals. The short fluorescence lifetime (2.6 ns) together with high quantum yield (50 %) of the MOL affords fast switching of the assembled WLEDs for efficient information encoding and transmission.

Abstract. We design a music player system based on white light emitting diode (LED) in visible light communication (VLC) system, using infrared remote to control. The transmitter loads music data from the storage device, decodes it and sends it to modulate LED arrays. The receiver transforms the optical signals to electrical signals, through the PIN circuits. After the amplifying circuits manage them, they are sent to a speaker to play. At the same time, a LCD will display the information of the music playing. The test shows that the music player can play fluently a variety of formats of music files and be easily controlled by the infrared remote control.
