Coding over random networks
نویسنده
چکیده
This report is based on the article [1] by Koetter and Kschischang. The authors introduced a novel approach for constructing codes by selecting a subset of a powerset of a vector space. With the code construction, they also defined an operator channel for code transmission. The codewords are vector subspaces. The data is transmitted by using one of the bases of such a subspace. The properties of codes of this type were studied. In this report, an overview of the operator channel, the codes and different bounds on the code’s error correction capabilities are given.

Rateless Coding over Wireless Relay Networks Using Amplify/Decode and Forward Relays
In this paper two different rateless transmissionschemes are developed. In the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination. Based on the analysis and simulation resultsprovided in this paper, the proposed method has bettertransmission time than the scheme which only the relay ...
متن کاملRelation Between RNA Sequences, Structures, and Shapes via Variation Networks
Background: RNA plays key role in many aspects of biological processes and its tertiary structure is critical for its biological function. RNA secondary structure represents various significant portions of RNA tertiary structure. Since the biological function of RNA is concluded indirectly from its primary structure, it would be important to analyze the relations between the RNA sequences and t...
متن کاملComboCoding: Combined Intra/Inter-Flow Network Coding for TCP over Multihop Lossy Wireless Networks
TCP over wireless networks is challenging due to high random losses and data-ACK interference. To address both problems, a new hybrid network coding scheme, ComboCoding, is proposed. ComboCoding combines intra-flow and inter-flow coding to provide robust communications over TCP in disruptive wireless networks. Intra-flow coding mitigates losses by using a modified random linear coding scheme th...
