“…Table 2 summarised the transmitted bits per symbol, spectral efficien- For DSOC systems, the IM/DD with photon-counting detectors are considered for the transceiver, i.e. IM and DD are assumed at the transmitter and receiver, respectively [49]. The receiver basically counts the number of photodetections by detecting the energy of the received signal during some observation interval and then makes a decision on the transmitted symbol using the photon counts [50].…”

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.

“…Even in an inter-satellite scenario, where atmospheric effects are absent, the pointing losses alone can frustrate the benefits offered by the optical frequencies. Hence, several studies have been conducted to model and analyze these losses [1], [9]- [12]. The extremely narrow optical beams, essential in deep space communications to maximize the received power, pose very tight requirements in terms of pointing accuracy.…”

Owing to the extremely narrow beams, a main issue in optical deep space communications is represented by miss-pointing errors, which may severely degrade the system performance and availability. In this paper, we address pointing losses in the case in which both the receiver and the transmitter are affected by angular errors. Pointing losses are evaluated through two approaches. The first approach is deterministic and only requires knowledge of a maximum angular error. The second approach requires knowledge of the angular error statistical distribution and tackles the problem from an outage probability viewpoint. These tools are then applied to analyze the impact of pointing losses in deep space optical links in which both terminals suffer from miss-pointing effects. The antenna gains are first optimized to maximize the effective system gain. The optimum antenna gains are then applied to evaluate maximum achievable ranges and to perform link design by means of optical link budgets.
