Source-Channel Coding in Networks
The aim of source coding is to represent information as accurately as possible using as few bits as possible and in order to do so redundancy from the source needs to be removed. The aim of channel coding is in some sense the contrary, namely to introduce redundancy that can be exploited to protect the information when being transmitted over a nonideal channel. Combining these two techniques le...
متن کاملExpansion Coding for Channel and Source Coding
A general method of coding over expansion is proposed, which allows one to reduce the highly non-trivial problems of coding over analog channels and compressing analog sources to a set of much simpler subproblems, coding over discrete channels and compressing discrete sources. More specifically, the focus of this paper is on the additive exponential noise (AEN) channel, and lossy compression of...

متن کاملSource-Channel Coding and Separation for Generalized Communication Systems
We consider transmission of stationary and ergodic sources over non-ergodic composite channels with channel state information at the receiver (CSIR). Previously we introduced alternate capacity definitions to Shannon capacity, including the capacity versus outage and the expected capacity. These generalized definitions relax the constraint of Shannon capacity that all transmitted information mu...
متن کاملShift-invariant Sparse Coding for Single Channel Blind Source Separation
In this paper we present results on single channel blind source separation based on a shift-invariant sparse coding model [1], [2] and [3]. This model learns a set of time-domain features from a single observation of the mixed signals. The found features can often be associated with a single source and can therefore be used to reconstruct the individual source signals. This is shown in this pap...
