The interference channel with degraded message sets (IC-DMS) refers to a communication model, in which two senders attempt to communicate with their respective receivers simultaneously through a common medium, and one sender has complete and a priori (noncausal) knowledge about the message being transmitted by the other. A coding scheme that collectively(More)
In this paper, the interference channel with common information (ICC), in which two senders need deliver not only private messages but also certain common messages to their corresponding receivers, is investigated. An achievable rate region for such a channel is obtained by applying a superposition coding scheme that consists of successive encoding and(More)
We investigate the fundamental limits of broadcast channels with cognitive relays. Specifically, we develop a new coding strategy and the associated achievable rate regions for the broadcast channel with two receivers and two additional cognitive relays. The new achievable rate regions exhibit potentially higher rates than existing schemes. We also consider(More)
In this paper, we consider full-duplex and half-duplex Gaussian relay channels where the noises at the relay and destination are arbitrarily correlated. We first derive the capacity upper bound and the achievable rates with three existing schemes: Decode-and-Forward (DF), Compress-and-Forward (CF), and Amplify-and-Forward (AF). We present two capacity(More)
We consider the discrete memoryIess two-sender-two-receiver interference channel in the setting where received signals are sent hack to their respective senders. The feedback signals enable each sender to crossly observe certain information transmitted by the other, and thus facilitate the senders to cooperate in resolving the remaining uncertainty in the(More)
This paper studies two-user causal cognitive radio channels, in which the secondary user has causal knowledge about the message being sent by the primary user. An inner bound on the capacity region of such channels is established by employing a coding strategy consisting of block Markov superposition and dirty paper encoding, and backward decoding. An(More)
—We study a special class of the cognitive radio channel in which the receiver of the cognitive pair does not suffer interference from the primary user. This class of cognitive Z-interference channels has not been investigated before. Previously developed general encoding schemes are complex as they attempt to cope with arbitrary channel conditions and thus(More)
This paper considers the three-node discrete memoryless relay channel with generalized feedback. In particular, two generalized feedback configurations are investigated. In the first configuration, the source is assumed to be able to actively collect feedback signals from the channel, while in the second one, the destination is assumed to be able to(More)
In mobility-aware of Internet of Things (IOT), according to the problem of data-aware and data-transmit which casued by nodes mobility and random. We propose the nodes social relations cognition algorithm which based on social network. Firstly, we would quantize the social relation of all nodes by introducing interconnection factor and distance factor.(More)
The velvet protein, VeA, is involved in the regulation of diverse cellular processes. In this study, we explored functions of FgVeA in the wheat head blight pathogen, Fusarium graminearum,using a gene replacement strategy. The FgVEA deletion mutant exhibited a reduction in aerial hyphae formation, hydrophobicity, and deoxynivalenol (DON) biosynthesis.(More)
