Feedforward carrier synchronization for pilotless bursts of DVB-RCS2
2014 9th International Symposium on Communication Systems, Networks & Digital Sign (CSNDSP), 2014This paper treats the exploration of carrier (frequency/phase) synchronization methods for use in second generation of Digital Video Broadcasting — Return Channel via Satellite (DVB-RCS2). This new standard specifies reference bursts consisting of very limited number of known symbols and operation of turbo code decoder at extremely low Signal to Noise ...

Evaluating Web Traffic Performance over DVB-RCS2
2013The web has undergone a radical change over time. Changes not only in the volume of data transferred, but also the way content is delivered to the user. Current web server architectures are often highly distributed and adapted for user interaction, with transactions characterised by multiple connections to multiple servers.

Low complexity carrier phase recovery for DVB-RCS2 standard
2012 International Conference on ICT Convergence (ICTC), 2012This paper introduces the simplified methods to reduce phase noise effect for DVB-RCS2 standard which was recently released as the next generation satellite VSAT(Very Small Aperture Terminal) system in Ku/Ka band. The relevant work deals with both linear and CPM modulation.

An efficient CPU‐GPU hybrid parallel implementation for DVB‐RCS2 receiver
Concurrency and Computation: Practice and Experience, 2018SummaryThe second‐generation digital video broadcasting return channel via satellite (DVB‐RCS2) is a promising real‐time wireless protocol that has been widely used in many applications, such as video conferences, video feeds, and video multicasting. However, the receiver end of DVB‐RCS2 is time consuming and should be accelerated by high‐performance ...

Performance Analysis of TCP New Reno Over Satellite DVB-RCS2 Random Access Links
IEEE Transactions on Wireless Communications, 2020In this paper, the performance evaluation of TCP New Reno over satellite DVB-RCS2 links with random access is analyzed. Based on the satellite system consisting of a large number of source-destination TCP New Reno pairs, a Markov chain model for a TCP connection is conducted.

DVB-RCS2 emulation system: To verify system level functions for multiple terminals
2015 International Conference on Information and Communication Technology Convergence (ICTC), 2015This paper describes a emulation system design based on DVB-RCS2 standard and verification of several system level functions. The proposed system can provide the testing environments of real performance evaluation using hardware type Hub system and VSATs, and it supports a lot of virtual VSATs created by VSAT emulators to test the return link access ...

Evaluation of the expansion of Joint IP Modem to support DVB-RCS2 (April 2012)
MILCOM 2012 - 2012 IEEE Military Communications Conference, 2012In 2006 the Defense Information Systems Agency (DISA) Joint Internet Protocol Modem (JIPM) Product Management Office (PMO) took the initiative to define a standard interoperable IP modem with transmission security. One of the prime motivations was to reduce the costs associated with operating the relatively large number of different proprietary IP ...

DVB-RCS2/S2 Testbed: A Distributed Testbed for Next-Generation Satellite System Design and Validation [PDF]
2014 7th Advanced Satellite Multimedia Systems Conference and the 13th Signal Processing for Space Communications Workshop (ASMS/SPSC), 2014 DVB-RCS2 is the second generation of DVB standards for the return link in interactive satellite systems, which is combined with the well consolidated DVB-S2 standard, applicable to forward links. This paper presents a DVB-S2/RCS2 testbed, able to reproduce all functionalities specified for higher and lower layers (HL and LL) of the protocol stack, down
