Joint Source-Channel Coding With Time-Varying Channel and Side-Information

Secure Joint Source-Channel Coding With Side Information

The problem of transmitting an i.i.d Gaussian source over an i.i.d Gaussian wiretap channel with an i.i.d Gaussian side information is considered. The intended receiver is assumed to have a certain minimum SNR and the eavesdropper is assumed to have a strictly lower SNR compared to the intended receiver. The objective is minimizing the distortion of source reconstruction at the intended receive...

Joint Source-Channel Coding on a Multiple Access Channel with Side Information

We consider the problem of transmission of several distributed correlated sources over a multiple access channel (MAC) with side information at the sources and the decoder. Source-channel separation does not hold for this channel. Sufficient conditions are provided for transmission of sources with a given distortion. The source and/or the channel could have continuous alphabets (thus Gaussian s...

Joint Source-Channel Coding for Arbitrarily Varying Wyner-Ziv Source and Gel’fand-Pinsker Channel

Joint Source-Channel Coding for the Arbitrarily Varying Wyner-Ziv Source and Gel'fand-Pinsker Channel

In this work we characterize the rate-distortion function of a Wyner-Ziv source, depending on an arbitrarily varying state, known non-causally at the encoder. We then consider the problem of joint source-channel coding of this source transmitted over an arbitrarily varying Gel’fand-Pinsker channel, where we assume that one jammer controls both, the source state sequence and the channel state se...

Zero-Error Source-Channel Coding With Side Information

We consider coding for transmission of a source through a channel without error when the receiver has side information about the source. We show that separate source and channel coding is asymptotically suboptimal in general. By contrast, in the case of vanishingly small probability of error, separate source and channel coding is known to be asymptotically optimal. For the zero-error case, we s...
