“…Finally, after the inclusion in the DVB-RCS2 specifications, the proposed CPM mode has been assessed for use in satellite mesh networks [20][21][22][23]. Although the proposed CPM scheme may require more complexity at the receiver side, the benefits deriving from the use of a nonlinear distortion resilient waveform in a mesh system with a large number of terminals, along with the rapid decreasing cost of baseband computational resources with respect to radio-frequency front-end, make CPM an attractive solution for the mesh scenarios as well as hub-spoke scenarios.…”

SUMMARY In this paper, we introduce the continuous phase modulations mode of the second‐generation broadband satellite communications return link Digital Video Broadcast Interactive Satellite System standard. Starting from a detailed discussion about the impairments faced in a typical broadband satellite system user set‐up, we introduce the waveform selection rationale, the design trade‐offs, and the waveform performance under realistic system assumptions. We show that the designed continuous phase modulations mode exhibits an excellent trade‐off between performance and robustness to nonlinear distortions at low and medium spectral efficiency thus suggesting its adoption for the consumer market profile of the Digital Video Broadcast Interactive Satellite System.

“…The results there provided represent a benchmark for the selection of new waveforms and the optimal configuration for such kind of networks. Results in [2] show how CPM can be considered as an efficient solution for satellite mesh networks with single or multi beams coverage for low to medium spectral efficiencies, due to its constant envelope and its resilience to impairments that affect transmissions, such as Adjacent Channel Interference (ACI), phase noise, uncompensated frequency offset, and transmitter non-linearities. Satellite mesh networks in hub-less configurations are in fact characterized by terminals with a small and low-cost antenna as well as a transmit amplifier with moderate to low output saturated power, which impose several constraints on the link budget.…”

This papers addresses the design of new energyefficient Continuous Phase Modulation (CPM) waveforms suitable for being adopted in satellite mesh networks that are characterized by the absence of the Hub, and by small antennas and power amplifiers with moderate to low output saturated power at the user terminal. In particular, a CPM modulation format concatenated with a proper convolutional code for low spectral efficiency values has been selected to implement an efficient waveform for power-limited scenarios. Performance results show the gain obtained with respect to the DVB-RCS2 CPM waveforms at higher spectral efficiency also when transmission techniques, such as Burst Repetition, are considered, and confirm the suitability of the new designed CPM waveforms for satellite hub-less scenarios.

“…However, for this SE range, CPM appears to be more cost efficient than LM, mainly because of the more relaxed requirements imposed on the radio frequencies (RF) front end of the terminal . On the other hand, LM appears to be a more appropriate solution for higher SE, because it allows to reach higher SE values with respect to the equivalent CPM schemes . In our current research and in order to increase the SE of CPM signals, the performance of multi‐amplitude CPM (MA‐CPM) signals is investigated for the first time in the context of satellite communication systems.…”

Summary This paper presents performance improvement techniques for the second‐generation digital video broadcast return channel via satellite air interface, which can be used for supporting future demands for Tbit/s traffic requirements. In particular, we have investigated minimum‐shift keying (MSK) type of continuous phase modulation (CPM) waveforms by considering both single‐carrier and multi‐carrier transmission and single‐amplitude and multi‐amplitude signals, which improve the spectral efficiency. In addition, we consider frame timing and synchronization techniques, which make synchronization more accurate and robust. Our research has shown that the MSK single‐carrier frequency‐division multiple access (SC‐FDMA) outperforms the quadrature phase‐shift keying SC‐FDMA in terms of resilience to distortion with the performance gap increasing when the amplifier shows a milder distortion. The performance of a multi‐amplitude CPM scheme, based upon the superposition of two single‐amplitude MSK signals at the radio frequencies level, is also investigated. In comparison with other equivalent linear modulation schemes, performance evaluation results have been shown that the proposed multi‐amplitude CPM scheme significantly improves the spectral efficiency in the presence of adjacent channel interference. Finally, we have proposed a viable and efficient methodology, which enables reliable and accurate timing and frequency synchronization for the SC‐FDMA satellite return link. This involves a combination of global positioning system (GPS)‐based pre‐compensation of differential timing between user terminals, preamble detection in an integrated random access channel, and user channel frequency estimation based on repetitive symbols in the time domain.
