Approaches to Layered Coding for Dual-Rate Wireless Video Transmission

Visual communications over wireless networks require the efficient and robust coding of video signals for transmission over wireless links having time-varying channel capacity. We compare several schemes for encoding video data into two priority streams, thereby enabling the transmission of video data over wireless links to be switched between two bit rates. An H.261 (p 64) algorithm is modifie...

The Benefit of Limited Feedback to Generation-Based Random Linear Network Coding in Wireless Broadcast

Random linear network coding (RLNC) is asymptotically throughput optimal in the wireless broadcast of a block of packets from a sender to a set of receivers, but suffers from heavy computational load and packet decoding delay. To mitigate this problem while maintaining good throughput, we partition the packet block into disjoint generations after broadcasting the packets uncoded once and collec...

Network-Coding-Aware Link Adaptation for Wireless Broadcast Transmission

We present a network-coding-aware link adaptation scheme for wireless broadcast transmission, which can achieve significantly higher throughput compared to schemes which always ensure correct decoding by the weakest link receiver. We evaluate the performance for the broadcast phase of a twoway relay channel based on average SNR feedback. If dynamic switch between the bit-wise XOR network coding...

Delay Optimal Scheduling for Chunked Random Linear Network Coding Broadcast

We study the broadcast transmission of a single file to an arbitrary number of receivers using Random Linear Network Coding (RLNC) in a network with unreliable channels. Due to the increased computational complexity of the decoding process (especially for large files) we apply chunked RLNC (i.e. RLNC is applied within non-overlapping subsets of the file). In our work we show the optimality of t...

Random linear network coding with ladder-shaped global coding matrix for robust video transmission

Robust video multicast in erasure networks using network coding (NC) to reduce the impact of packet loss is studied in this paper. In our proposed solution, random linear network coding (RLNC) is adopted at intermediate nodes of the network. RLNC linearly combines a group of packets by randomly selecting weighting coefficients on a finite field, and the loss of an RLNC-coded packet is equivalen...
