We consider the general relay channel. For this setup, the best achievability result was derived by Cover and ElGamal, in theorem 6 of their paper from 1979. In this work we apply...
Abstract-- The capacity of a class of deterministic relay channels with the transmitter input X, the receiver output Y , the relay output Y1 = f(X, Y ), and a separate communicatio...
Scalability and extended lifetime are two critical design goals of any large scale wireless sensor network. A two-tiered network model has been proposed recently for this purpose....
The secrecy capacity is developed for a class of relay channels with orthogonal components and a passive eavesdropper node. The relay and destination receive signals from the sourc...

For wireless networks with multiple sources, an omnidirectional relay scheme is developed, where each node can help relay multiple messages in different directions. This is accomp...
This paper considers a multiple input multiple output (MIMO) two-way relay channel, where two nodes want to exchange data with each other using multiple relays. An iterative algor...
Abstract. Relay attacks are a major concern for RFID systems: during an authentication process an adversary transparently relays messages between a verifier and a remote legitimate...
The performance of user-cooperation in a multi-access network is compared to that of using a wireless relay. Using the total transmit and processing power consumed at all nodes as...

In a distributed space-time coding scheme, based on the relay channel model, the relay nodes co-operate to linearly process the transmitted signal from the source and forward them ...
Abstract-- We consider the problem of two transmitters wishing to exchange information through a relay in the middle. The channels between the transmitters and the relay are assume...
