| This paper presents a rate-adaptive error control (RAEC) protocol for multimedia multicast services in satellite-terrestrial hybrid networks. The proposed scheme considers user fairness to multicast group and adapts code rate according to the channel conditions. In order to provide fairness perceived by user application, a packet is transmitted via satellite, while the retransmission of the p...

Wireless communication is an essential component of public safety operations [1,2]. First responders have benefited from many technical advances in the wireless arena in recent years including new modes for voice and data communications, cellular and satellite communications, and wireless local area networks (WLAN). At the same time, this profusion of new technology has aggravated a looming cri...

Driven by the ever increasing penetration and proliferation of data-driven applications, a new generation wireless communication, sixth (6G) mobile system enhanced artificial intelligence, has attracted substantial research interests. Among various candidate technologies 6G, low Earth orbit (LEO) satellites have appealing characteristics ubiquitous access. However, costs satellite communication...

The utilisation of distributed medical intelligence can contribute significantly to the continuous improvement of patient care and accelerates the qualification process of the medical staff. An efficient way of realisation is the use of satellite networks for telemedical applications, as satellite communication has some distinct advantages over terrestrial communication channels: mesh topology ...

The article is devoted to the estimation of threshold values, regulated by ITU, which determine the necessity of satellite networks coordination in the Ku band. Maximum capacity of geostationary orbit (GEO) for different diameters of earth station antennas, operating in standard DVB-S2 accounting the limitations caused by the parameters of existing satellite networks equipment, is determined. O...

The challenge of future mobile multimedia networks is to provide worldwide tetherless communication services. Low Earth Orbit-Mobile Satellite Systems (LEO-MSSs) will play a significant role by filling the coverage gaps of future generation terrestrial cellular networks. This lecture presents research results on demand-assignment Medium Access Control (MAC) schemes able to share efficiently LEO...

A crucial issue in the next-generation satellite-based communication systems is the satellite on-board reallocation of information which requires digital flexible frequency-band reallocation (FBR) networks. This paper introduces a new class of flexible FBR networks based on variable oversampled complex-modulated filter banks (FBs). The new class can outperform the previously existing ones when ...
