We are interesting in the error exponent for source coding with fidelity criterion. For each fixed distortion level ∆, the maximum attainable error exponent at rate R, as a function of R, is called the reliability function. The minimum rate achieving the given error exponent is called the minimum achievable rate. For memoryless sources with finite alphabet, Marton (1974) gave an expression of t...

In this paper, the secrecy problem in the state dependent causal cognitive interference channel is studied. The channel state is non-causally known at the cognitive encoder. The message of the cognitive encoder must be kept secret from the primary receiver. We use a coding scheme which is a combination of compress-and-forward strategy with Marton coding, Gel’fand-Pinsker coding and Wyner’s wire...

The capacity of multiuser wireless network, unclear for many years, has always been a hot research topic. Many different operation schemes and coding techniques have been proposed to enlarge the achievable rate region. And omnidirectional relay scheme is one of them. This thesis mainly works on the achievable region of the all-source all-cast network with omnidirectional relay scheme. In order ...

We consider three capacity definitions for a channel with channel side information at t h e receiver. T h e capacity is the highest rate asymptotically achievable. T h e outage capacity is t h e highest rate asymptotically achievable with a given probability of decoder-recognized outage. The expected capacity is t h e highest expected rate asymptotically achievable using a single encoder a n d ...

We propose a new coding technique based on nested coset codes and derive a new achievable rate region for a general three user discrete memoryless broadcast channel (DMBC). We identify an example of a three user binary broadcast channel for which the proposed achievable rate region strictly outperforms that obtained by a natural extension of Marton’s [1] rate region. As a step towards deriving ...
