A Simply Described Achievable Rate Region for the Cognitive Radio Channel

چکیده

A simply described achievable rate region is obtained for the genie-aided cognitive radio channel using the Han-Kobayashi celebrated jointly decoding strategy for the interference channel and the Gel’fandPinsker coding scheme for channels with side information known at the transmitter, and then is simplified by Fourier-Motzkin elimination. The obtained achievable rate region (i) extends the Chong-Motani-Garg region for the interference channel to the cognitive channel and (ii) is a simplified description of Devroye-Mitran-Tarokh rate region for the genie-aided cognitive radio channel.

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...

Comments on "Achievable Rates in Cognitive Radio Channels"

In a premier paper on the information-theoretic analysis of a two-user cognitive interference channel (CIC) [1], Devroye et al. presented an achievable rate region for the two-user discrete memoryless CIC. The coding scheme proposed by Devroye et al. is correct but unfortunately some rate-terms in the derived achievable rate region are incorrect (in fact incomplete) because of occurring some mi...

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...

An Achievable Rate Region for Cognitive Radio Channel With Common Message

The cognitive radio channel with common message (CRCC) is considered. In this channel, similar to the cognitive radio channel (CRC), we have a cognitive user which has full non-causal knowledge of the primary message, and like the interference channel with common message (ICC), the information sources at the two transmitters are statistically dependent and the senders need to transmit not only ...
