We consider a communication system where two transmitters wish to exchange information through a central relay. The transmitter and relay nodes exchange data over synchronized, average power constrained additive white Gaussian noise channels with a real input with signal-to-noise ratio (SNR) of snr. An upper bound on the capacity is 1/2 log(1 + snr) bits… (More)

We study the joint source-channel coding problem of transmitting a Gaussian source over a Gaussian channel in two cases: (i) the presence of interference known only to the transmitter and (ii) in the presence of side information about the source known only to the receiver. We introduce hybrid digital analog forms of the Costa and Wyner-Ziv coding schemes.… (More)

We consider the problem of broadcasting kldr samples of an independent identically distributed (i.i.d) Gaussian source to two users in n = lambdakldr uses of an AWGN channel. We develop a framework which shows a duality between a source-channel coding scheme for the case of lambda > 1 and that for lambda < 1. Using this duality, we derive a scheme for… (More)

In this work we study encoding/decoding schemes for the transmission of a discrete time analog Gaussian source over a Gaussian wiretap channel. The intended receiver is assumed to have a certain minimum signal to noise ratio (SNR) and the eavesdropper is assumed to have a strictly lower SNR compared to the intended receiver. For a fixed information leakage… (More)

The project can be (i) an in-depth study of key papers in an area not covered in class, (ii) a solution to an open problem, or (iii) a new problem with some preliminary results. The project needs to be in the general area of network information theory. • Grouping: Projects can be done in groups of 1 to 2 students. A list of recommended projects is provided… (More)
