In this paper, we investigate the downlink transmission of a non-orthogonal multiple access (NOMA)-based integrated terrestrial-satellite network, in which the NOMA-based terrestrial networks and the satellite cooperatively provide coverage for ground users while reusing the entire bandwidth. For both terrestrial networks and the satellite network, multi-antennas are equipped and beamforming techniques...
The coordination between satellite communications and terrestrial mobile networks is promising to enable a globally ubiquitous broadband wireless coverage. It also provides an opportunity to share the spectrum between satellites and terrestrial networks, to alleviate the spectrum scarcity problem facing in both systems. Particularly in a coordinated satellite-terrestrial network (CSTN), the co-channel...
The integrated and/or hybrid satellite and terrestrial network has become more and more important because of its broad application prospect and has received considerable attention. At the same time, the integrated network also brings many challenges, especially the problem of interference. Due to the lack of frequency spectrum, frequency reuse is considered in the satellite network and the terrestrial...
Amplitude phase-shift keying (APSK), especially 16APSK and 32APSK modulations, have been efficiently applied into satellite broadcasting and communications, such as DVB-S2, which endows the system with high spectrum efficiency and transmission rate. However, fewer design about the trellis coding and modulation based on APSK has been reported so far. In this paper, the symmetric and asymmetric TCM...
DVB-S2 based satellite broadcast system benefits from adaptive coding and modulation (ACM) for improving the bandwidth efficiency, which yields physical layer signaling (PLS) codes in the head of the physical frame. However, with the increasing types of ACM, the reserved assignable PLS codes will be soon exhausted. In this paper, the extension design of PLS codes is proposed, which will meet the requirement...
