Lower Bounds on the Capacity of Gaussian Relay Channel
It has been shown recently that the overall throughput of dense wireless networks can increase significantly when wireless nodes collaborate in transmission of different packets. In this paper, we focus on a simple network ...
Joint signaling strategies for approaching the capacity of twisted-pair channels
A technique is presented for jointly optimizing the signaling in the two directions of transmission on a twisted-pair communications channel. It is then applied to twisted-pair channel models with monotonic channel response ...
On the Capacity of `Cheap' Relay Networks
We consider the communication problem in a multi-hop relay network where the intermediate relay nodes cannot transmit and receive at the same time. The motivation for this assumption comes from the fact that current radios ...
The Capacity of Average and Peak Power Constrained Fading Channels with Channel Side Information
We derive the ergodic capacity of discrete-time fading channel with additive Gaussian noise subject to both peak and average power constraint. The average power can be interpreted as the cost that we incur to achieve a ...
On Capacity of Gaussian â Cheapâ Relay Channel
In this paper, we derive the capacity of the Gaussian degraded â cheapâ relay channel, consisting of nodes using â cheapâ radios operating in TDD mode when transmitting and sending in the same frequency band. The TDD ...
