Rateless coding transmission over multi-state dying erasure channel for SATCOM
Satellite communication (SATCOM) systems have attracted great attention from academic and industrial communities in recent years, and huge amount of data delivery over satellite downlinks is considered as a promising service in emerging 5G networks, such as multimedia broadcasting. Nevertheless, due to intermittent connections from LEO or MEO satellite to earth station, and high dynamic channel...
متن کاملJoint Cache-Channel Coding over Erasure Broadcast Channels
We consider a cache-aided communications system in which a transmitter communicates with many receivers over an erasure broadcast channel. The system serves as a basic model for communicating on-demand content during periods of high network congestion, where some content can be preplaced in local caches near the receivers. We formulate the cacheaided communications problem as a joint cache-chan...
متن کاملNetwork Coding Over SATCOM: Lessons Learned
Satellite networks provide unique challenges that can restrict users’ quality of service. For example, high packet erasure rates and large latencies can cause significant disruptions to applications such as video streaming or voice-overIP. Network coding is one promising technique that has been shown to help improve performance, especially in these environments. However, implementing any form o...
متن کاملRateless Coding for Block Fading Channels Using Channel Estimation Accuracy
The design of efficient rateless coding schemes for multicast applications in wireless environments is investigated. First, the digital fountain paradigm for non-ergodic channels is introduced by making use of the dynamic-decoding nature of rateless codes that allows them to adapt opportunistically the code rate to the channel realization (assumed unknown at the transmitter). The information th...
متن کاملRateless Coding for Non-Ergodic Channels with Decoder Channel State Information
Rateless coding has recently been the focus of much practical as well as theoretical research. In this paper we argue that rateless codes find a natural application in non-ergodic channels where the channel law varies unpredictably. Such unpredictability means that to guarantee reliability block-codes are limited by worst-case channel variations. However, the dynamic-decoding nature of rateless...
