Lossy Joint Source-Channel Coding Using Raptor Codes
The straightforward application of Shannon’s separation principle may entail a significant suboptimality in practical systems with limited coding delay and complexity. This is particularly evident when the lossy source code is based on entropy-coded quantization. In fact, it is well known that entropy coding is not robust to residual channel errors. In this paper, a joint source-channel coding ...
متن کاملDistributed Joint Source-Channel Coding with Raptor Codes for Correlated Data Gathering in Wireless Sensor Networks
Correlated data gathering in body area networks calls for systems that perform efficient compression and reliable transmission of the measurements, while imposing a small computational burden at the sensors. Highly-efficient compression mechanisms, e.g., adaptive arithmetic entropy encoding, do not address the problem adequately, as they have high computational demands. In this paper, we propos...
متن کاملLossy Joint Source-Channel Coding for Energy Harvesting Communication Systems
In this work, we study the problem of lossy joint source-channel coding in an energy harvesting single-user communication system with causal energy arrivals, where the energy storage unit may have leakage. In particular, we investigate the achievable distortion in the transmission of a single source with arbitrary alphabets via an energy harvesting transmitter over a point-to-point channel. We ...
متن کاملA Practical Approach to Lossy Joint Source-Channel Coding
This work is devoted to practical joint source channel coding. Although the proposed approach has more general scope, for the sake of clarity we focus on a specific application example, namely, the transmission of digital images over noisy binary-input output-symmetric channels. The basic building blocks of most stateof the art source coders are: 1) a linear transformation; 2) scalar quantizati...
متن کاملSystematic Lossy Source/Channel Coding
The fundamental limits of “systematic” communication are analyzed. In systematic transmission, the decoder has access to a noisy version of the uncoded raw data (analog or digital). The coded version of the data is used to reduce the average reproduced distortion D below that provided by the uncoded systematic link and/or increase the rate of information transmission. Unlike the case of arbitra...
