Error Recovery- Channel Coding and Packetization
Distributed Speech Recognition (DSR) systems rely on efficient transmission of speech information from distributed clients to a centralized server. Wireless or network communication channels within DSR systems are typically noisy and bursty. Thus, DSR systems must utilize efficient Error Recovery (ER) schemes during transmission of speech information. Some ER strategies, referred to as forward ...
متن کاملRateless distributed source code design
Over the past decade, rateless codes, i.e., digital fountain codes, have emerged as an efficient and robust solution for reliable data transmission over packet erasure networks and a particularly suitable one for multicasting and broadcasting applications where users may experience variable channel conditions and packet loss rates, such as mobile environments. Luby Transform (LT) and Raptor cod...
متن کاملDistributed Lossy Source Coding Using BCH-DFT Codes
Distributed source coding, separate encoding (compression) and joint decoding of statistically dependent sources, arises in an increasing number of applications like sensor networks and multiview video coding. Many of those applications are highly interactive, requiring the development of low-delay, energy-limited communication and computing schemes. Currently, this compression is performed by ...
متن کاملScalable Joint Source-Network Error Control Coding for Overlay Video Streaming
Abstract— In this paper, we investigate a joint source-network coding scheme for adapting a scalable video bitstream. Both embedded bitstream and error-control codes are easily and precisely adapted in a multidimensional way at intermediate overlay nodes to satisfy multiple heterogeneous users without complex transcoding. These distributed nodes form an overlay service network, and adapt both t...
متن کاملExperimental Study of Application Specific Source Coding for Wireless Sensor Networks
The energy bottleneck in Wireless Sensor Network(WSN) can be reduced by limiting communication overhead. Application specific source coding schemes for the sensor networks provide fewer bits to represent the same amount of information exploiting the redundancy present in the source model, network architecture and the physical process. This paper reports the performance of representative codes f...
