“…In the previous papers dealing with NLOS optical communication, modulations such as on-off-keying (OOK), pulse position modulation (PPM), dual-head pulse interval modulation (DH-PIM), frequency-shift keying (FSK), spectral amplitude coding (SAC), and others were used. The choice of the DPIM modulation is quite justified, since it was shown, for example, in [29] that this type of communication modulation potentially allows more symbols to be transmitted per unit time than, for example, OOK.…”

“…At the beginning of the 21st Century, the development of small-sized laser sources and highly sensitive optical receivers has caused a sharp growth in the interest of specialists in studying the feasibility of NLOS wireless optical communications [24]. We consider the papers [25][26][27][28][29][30][31] to be the most-important from the viewpoint of developing the theory and experimental studies of NLOS communication feasibility. As a part of the work on terrestrial NLOS communications in the open atmosphere, the following most-important results were obtained: (1) methods for statistical simulation of the impulse response of a communication channel have been developed; (2) analytical equations have been proposed for the single scattered part of the impulse response; (3) interpolation equations have been proposed for the impulse response and the path loss; (4) the received signal duration as a function of a wide range of optical-geometric conditions has been assessed; (5) equations have been proposed for calculating the bit error rate (BER), symbol error rate (SER), and package error rate (PER) for a wide range of modulation methods; (6) the dependence of the BER, signal-to-noise ratio (SNR), and maximum data rate on a wide range of optical and geometric conditions and source parameters for the main information encoding methods has been assessed; (7) the effect of turbulence on the path loss under day and night conditions has been evaluated.…”

An opto-electronic system for non-line-of-sight (NLOS) communication using scattered laser radiation for unmanned aerial vehicle (UAV)–ground and ground–UAV schemes at a wavelength of λ = 450 nm and a ground–UAV scheme at a wavelength of λ = 510 nm are described. The symbol error rate (SER) and its standard deviation were analyzed for different schemes of the communication channel. The transceiver system included a laser source with a power supply, a modulator, a lens refractor, a bandpass filter, a photomultiplier tube (PMT), a demodulator, and a receiving computer. The experimental data obtained at nighttime showed that the NLOS atmospheric optical communication at a wavelength of λ = 450 nm was feasible for the UAV–ground scheme at a baseline distance of up to 150 m for a UAV with a transmitter at a height of 10 m and at a baseline distance of up to 125 m for a UAV at a height of 20 m. For the ground–UAV scheme, stable communication was observed at baseline distances of up to 50 m for a UAV with a receiver at a height up to 30 m. The NLOS atmospheric optical communication at a wavelength of 510 nm was obtained for the ground–UAV scheme at baseline distances of up to 100 m for a UAV with a receiver at a height up to 45 m, as well as at baseline distances of up to 385 m for UAV flying at a height up to 20 m.

“…Each control path includes a detector and filter connected in series. As a detector, the conditioner model can contain various types of demodulators depending on the type of modulation used at the physical level: on-off keying (OOK), or pulse-position modulation (PPM); in addition, digital pulse interval modulation (DPIM and dual-head DPIM, DH-DPIM), which do not require external synchronization of the transmitter and receiver [18][19][20][21][22][23] y2y3 , where y1 is the level number, y2 is the number of the unit to which the signal belongs; y3 is the signal identifier. The identifier y3 can take the following alphabetic and numerical designations: 1 -input signal of the unit, 2 -output, y -control signal CU, f -CPs of FFR circuit, b -CPs of FBR circuit.…”

The use of mobile ad hoc networks (MANET) with a nonline-of-sight (NLOS) communication channel in the UV-C spectral range from 200 to 280 nm is advisable in a number of conditions when traditional radio communication is ineffective (strong interference due the electromagnetic background interference, challenging terrain etc.). The detailed development of a data transport physical layer model is required to create reliable and efficient MANETs with a UV channel; the model is determined by the operating conditions of the networks. A hierarchical model for the conditioning of information signals has been developed, and also an optical transmitter and an optical receiver in order to provide their analytical description and further analysis; the model allows one to present various options for communication channels. Analytical expressions are obtained for the transfer function of the generalized hierarchical model for an arbitrary number of open levels of the hierarchy. The energy characteristics of the UV communication system are calculated at various noise levels depending on the geometric parameters of the UV channel: communication range and azimuthal deviation of the transmitter and receiver.

“…Digital pulse interval modulation (DPIM) can modulate the same number of bits per symbol as an even-order PPM but does not require symbol synchronization. It is also important that DPIM uses fewer time slots per symbol than PPM and thus requires less bandwidth [15][16][17][18][19][20]. As PPM, DPIM has higher energy efficiency than OOK.…”

Wireless optical communication systems allow reliable communication in the ultraviolet (UV) range, and protected from intentional suppression and interception, both in the presence and in the absence of direct visibility between the transmitter and the receiver. Currently, the actual and insufficiently explored direction is the development and research of mobile ad-hoc networks (MANET) with a UV communication channel. To analyze the capacity of a mobile network of UV communications with different spatial orientation of network nodes, it is necessary to take into account not only their coordinates and elevation angles but also azimuths. NLOS UV bandwidth models have been developed using three types of modulation: on-off keying (OOK), pulse-phase modulation (PPM), digital pulse interval modulation (DPIM) with a different number of guard intervals. The noted advantages of DPIM, which are most important for the implementation of a mobile self-organizing network with a UV channel, are: it does not require symbolic synchronization of the transmitter and receiver, it requires a smaller frequency band compared to PPM, it has a higher energy efficiency compared to OOK. A parametric approximation of losses in the NLOS UV channel has been performed, taking into account the azimuthal deviations of the transmitter and receiver for specific parameters of the communication system. Has been done a performance simulation of the MANET network with an ultraviolet communication channel Has been calculated values of the bit error rate (BER), and bit rate for a system with different types of modulation with low, medium, and high noise levels in the channel. With the use of parametric approximation of losses in the channel, are analyzed the BER and the bitrate of the UV communication system with an azimuthal deviation within 30 degrees. Based on the obtained simulation results, prospects for the further development of mobile self-organizing networks with a UV channel are indicated to improve their reliability and performance.
