“…Previously, the performance of SiPM receivers has been predicted [8][9][10][11][12] or determined experimentally [13][14][15][16][17][18][19][20][21]. The experimental results include transmitting 400 Mbps at a bit error rate (BER) of 1.8x10 -3 to a custom-made 2.8 mm by 2.6 mm SiPM with an irradiance of 1.4 mWm -2 [17].…”

In this paper, the performance of a wide field of view VLC receiver that includes a silicon photomultiplier (SiPM) is reported. In particular, a receiver field of view of ±45 o and On-Off keying data rates of 1.8 Gbps are demonstrated in 500 lux of ambient light. These results are achieved by combining optical absorption filters with a 6 mm by 6 mm SiPM. By absorbing ambient light between 450 nm and 750 nm these filters ensure that the SiPM is not saturated and reduces the transmitter power needed to support the required data rate. Unlike other optical filters the performance of absorption filters is not sensitive to angle of incidence. Consequently, the FOV is explained by a combination of the changes to the receiver's projected area, the path length of light in the filters and reflections from the filter surfaces. In addition, the results of the calculations, described by the IEC 62471:2006 safety standard, needed to determine the eye safety of a transmitter are reported. These calculations and the resulting irradiance levels available in a representative office scenario are used to show that data rates of more than 1 Gbps could be achieved with eye safe transmitters.

“…The transmitted signals of OWC have to be real and unipolar owing to the inherent nature of an optical light emitting diode (LED) transmitter. To meet this criterion, pulse amplitude modulated discrete multitone (PAM-DMT), asymmetrically clipped optical OFDM (ACO-OFDM), flip OFDM, direct current-biased optical OFDM (DCO-OFDM) have been extensively discussed in the literature [2]- [6]. However, these schemes have some drawbacks.…”

This paper proposes a cyclic shifted layer asymmetrically clipped optical orthogonal frequency division multiplexing system (CS-LACO-OFDM) for optical wireless communications. The transmitted signal in CS-LACO-OFDM is generated by combining the signal of the first layer and signals of the remaining L-1 layers with cyclic shift equivalents, where L is the number of the CS-LACO-OFDM layers. In particular, the sets of cyclic shift value in CS-LACO-OFDM are modulated on the odd subcarriers of the first layer with complex-valued symbols. Information on cyclic shift sets can be easily detected with the help of modulated symbols conveyed in the first layer without increasing the receiver complexity. Simulation results show that the CS-LACO-OFDM has a similar peak-to-average power ratio performance as LACO-OFDM with separate selective mapping scheme when the number of candidate signals is the same but at remarkably low computational complexity. Furthermore, the average bit error rate of CS-LACO-OFDM over all layers is minimized by the proposed optimal optical power allocation. INDEX TERMS Hybrid modulation, peak-to-average power ratio, cyclic shift, visible light communication, layer asymmetrically-clipped optical orthogonal frequency division multiplexing.

To realize a long-distance underwater communication by using low-cost light emitting diode (LED) and single photon avalanche diode (SPAD), we proposed a method for recovering clock and data directly from discrete random pulse sequences output by SPAD. On this basis, a new communication model is established, taking into account not only fluctuations in photon flux and quantum efficiency of photon detection in a time-slot, but also the phase difference of the recovered clock caused by it. A photon-counting underwater optical wireless communication (UOWC) system was built. The effects of the system setting parameters such as the number of gating signals, synchronous character length and baud rate on the average bit error rate (BER) were verified by experiments. The experimental results show that under condition of only average 10 photons in one time-slot, photoncounting UOWC with a BER of 3.51 × 10 −4 and a baud rate of 1 Mbps can be achieved.
