چکیده

Abstruct-A new achievable rate region for the general interference channel which extends previous results is presented and evaluated. Tbe technique used is a generalization of superposition coding to the multivariable case. A detailed computation for tbe Gaussian cbaunel case clarifies to wbat extent the new region improves previous ones. The capacity of a class of Gaussian interference channels is also established.

Achievable Secrecy Rate Regions of State Dependent Causal Cognitive Interference Channel

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...

On The Secrecy of the Cognitive Interference Channel with Channel State

In this paper the secrecy problem in the cognitive state-dependent interference channel is considered. In this scenario we have a primary and a cognitive transmitter-receiver pairs. The cognitive transmitter has the message of the primary sender as side information. In addition, the state of the channel is known at the cognitive encoder. Hence, the cognitive encoder uses this side information t...

An Achievable Rate Region for the Gaussian Interference Channel

Abstract An achievable rate region for the Gaussian interference channel is derived using Sato’s modified frequency division multiplexing idea [1] and a special case of Han and Kobayashi’s rate region (denoted by G′ in [2]). We show that the new inner bound includes G′, Sason’s rate region D [3], as well as the achievable region via TDM/FDM [4], as its subsets. The advantage of this improved in...

On the Achievable Rate-Regions for the Gaussian Two-way Diamond Channels

In this channel,we study rate region of a Gaussian two-way diamond channel which operates in half-duplex mode. In this channel, two transceiver (TR) nodes exchange their messages with the help of two relay nodes. We consider a special case of the Gaussian two-way diamond channels which is called Compute-and-Forward Multiple Access Channel (CF-MAC). In the CF-MAC, the TR nodes transmit their mes...

The Expected Achievable Distortion of Two-User Decentralized Interference Channels

This paper concerns the transmission of two independent Gaussian sources over a two-user decentralized interference channel, assuming that the transmitters are unaware of the instantaneous CSIs. The availability of the channel state information at receivers (CSIR) is considered in two scenarios of perfect and imperfect CSIR. In the imperfect CSIR case, we consider a more practical assumption of...
