A hybrid multiple pulse amplitude and position modulation (H-MPAPM) scheme based on gradual multi-pulse pulse-position modulation (G-MPPM) and multi-level pulse amplitude modulation (M-PAM) schemes is proposed for deep-space optical communication. In this scheme, transmitted information is conveyed by different combinations of the positions and amplitudes of multiple optical pulses. The performance of the proposed scheme with multi-pulse pulse-position modulation (MPPM), G-MPPM and multiple pulse amplitude and position modulation (M-PAPM) schemes in terms of the number of transmitted symbols, data rate, symbol error rate (SER), bit error rate (BER), bandwidth utilization efficiency and power requirements are studied in this work. Our results reveal that, at the same frame size, the proposed scheme allows much more symbols per frame transmission, achieves higher transmission energy and further enhance the bandwidth utilization efficiency of MPPM, G-MPPM and M-PAPM schemes. Moreover, compared to the MPPM and G-MPPM, the proposed scheme achieves lower levels of SERs but at the expense of peak power levels. Furthermore, the proposed scheme outperforms G-MPPM and MPPM schemes by approximately 1 and 2 dB at a BER of 10 −6 , respectively. In addition, the analytical expressions for the BER and SER of the proposed scheme are validated using Monte Carlo (MC) simulations.

Modeling of multiple-scattering channels in atmospheric turbulence is essential for the performance analysis of long-distance non-line-of-sight (NLOS) ultraviolet (UV) communications. Existing works on the turbulent channel modeling for NLOS UV communications either ignored the turbulence-induced scattering effect or erroneously estimated the turbulent fluctuation effect, resulting in a contradiction with reported experiments. In this paper, we establish a comprehensive multiple-scattering turbulent channel model for NLOS UV communications considering both the turbulence-induced scattering effect and the turbulent fluctuation effect. We first derive the turbulent scattering coefficient and turbulent phase scattering function based on the Booker-Gordon turbulent power spectral density model. Then an improved estimation method is proposed for both the turbulent fluctuation and the turbulent fading coefficient based on the Monte-Carlo integration approach. Numerical results demonstrate that the turbulence-induced scattering effect can always be ignored for typical UV communication scenarios.Besides, the turbulent fluctuation will increase as either the communication distance, the elevation angle, or the divergence angle increases, which is compatible with existing experimental results. Moreover, we find that the probability density of the equivalent turbulent fading for multiple-scattering turbulent channels can be approximated as a Gaussian distribution.

“…That is, the received signal can be detected by employing a conventional photodiode or a continuous waveform detector [6], [9], [24]. It should be noted, however, that if the received signal is weak, a photon counting receiver can be employed as the received signal obeys a Poisson distribution [25].…”

Petahertz frequency bands have a unique characteristic of atmospheric scattering that enables non-line-of-sight (NLOS) communications. In this paper, we analyze the performance of petahertz wireless communications (PWC) with a novel statistical model derived over a multiuser interferencelimited optical turbulence channel. Specifically, we derive a novel probability density function of the received signal-to-interference ratio when the distribution of the received signal is quantified with each scattered path following a Málaga distribution. Moreover, novel closed-form expressions for the outage and the bit error probabilities are derived in the interference-limited PWC. The outage performance is evaluated over non-identical Málaga fading channels, where the fading characteristics of the transmitter and the interferer are different. We also investigate the achievable capacity of the multiuser interference-limited PWC over Málaga fading channels. The analytical results obtained are corroborated with simulation results. It is shown that the analysis performed with the proposed statistical model is reliable and accurate and thus the statistical model can be useful for emerging multiuser interference-limited petahertz wireless communications.INDEX TERMS Optical communications, outage probability, signal-to-interference ratio, turbulence fading.
