“…The beam of satellite directly covers to M ground users, generating a sparse usersubcarriers matrix G K×M in the form of an overload (i.e., the information of user n and user m is mapped to the K sparse subcarriers (SC), which satisfies the relationship of M > K) 2 . One frequency band serves all beams in common, i.e., the mode transmission of single multiplexing [40].…”

This paper investigates the application of a unified non-orthogonal multiple access framework in beam hopping (U-NOMA-BH) based satellite communication systems. More specifically, the proposed U-NOMA-BH framework can be applied to code-domain NOMA based BH (CD-NOMA-BH) and power-domain NOMA based BH (PD-NOMA-BH) systems. To satisfy dynamic-uneven traffic demands, we formulate the optimization problem to minimize the square of discrete difference by jointly optimizing power allocation, carrier assignment and beam scheduling. The non-convexity of the objective function and the constraint condition is solved through Dinkelbach's transform and variable relaxation. As a further development, the closed-from and asymptotic expressions of outage probability are derived for CD/PD-NOMA-BH systems. Based on approximated results, the diversity orders of a pair of users are obtained in detail. In addition, the system throughput of U-NOMA-BH is discussed in delay-limited transmission mode. Numerical results verify that: i) The gap between traffic requests of CD/PD-NOMA-BH systems appears to be more closely compared with orthogonal multiple access based BH (OMA-BH); ii) The CD-NOMA-BH system is capable of providing the enhanced traffic request and capacity provision; and iii) The outage behaviors of CD/PD-NOMA-BH are better than that of OMA-BH.

“…Dual-band or dual-polarized antennas can support two-color reuse scheme for satellite communication applications [25]. In contrast, antennas with simultaneous dual-band and dualpolarization characteristics compatible with four-color reuse strategy can further improve the spectral efficiency particularly for high throughput applications [3].…”

“…The current broadband services are provided by the satellite operators using state of the art multi-beam satellite systems where the resulting inter-beam interference is mitigated using four colour frequency reuse scheme [1], [2]. However, the demand for broadband services is evolving and in recent years, due to mobile nature of the users, broadband demand is more dynamic than ever [3].…”

In recent years, dynamic traffic demand requisites have driven the satellite communication service providers to implement reconfigurable demand-driven features to align the delivered throughput with the temporal and geographical variations of the traffic demand. Also, in current interference-limited High Throughput Satellite (HTS) systems, the resulting inter-beam co-channel interference can be mitigated by carefully performing precoding and user scheduling. Unfortunately, the conventional user scheduling algorithms fail to provide demand satisfaction for dynamic traffic demand requisites. Hence, in this paper, we focus on the user scheduling design for precoded satellite systems where both co-channel interference and user demands are taken into account. In particular, we first classify the sectors in each beam according to the interference they may cause to neighboring beams. Next, we formulate the scheduling problem such as the activation of neighboring beam sectors is avoided while proportionally dwelling on the sectors based on their traffic demands. The supporting numerical results for different demand distribution profiles validate the effectiveness of proposed interference-aware demand-based user scheduling over conventional scheduling techniques.INDEX TERMS Multi-beam high throughput satellite systems, beam pattern, beam footprint, DVB-S2X, precoding.
