Bounds and Capacity Theorems for Cognitive Interference Channels with State
Bounds and Capacity Theorems Cognitive Interference Channels State Information Theory
2012/7/9
A class of cognitive interference channel with state is investigated, in which two transmitters (transmitters 1 and 2) communicate with two receivers (receivers 1 and 2) over an interference channel. ...
De-randomizing Shannon: The Design and Analysis of a Capacity-Achieving Rateless Code
De-randomizing Shannon Analysis of a Capacity-Achieving Rateless Code Information Theory
2012/6/15
This paper presents an analysis of spinal codes, a class of rateless codes proposed recently. We prove that spinal codes achieve Shannon capacity for the binary symmetric channel (BSC) and the additiv...

address the research needs of spatial data provision in Europe. With a ...
Approaching Capacity at High-Rates with Iterative Hard-Decision Decoding
Approaching Capacity High-Rates Iterative Hard-Decision Decoding
2012/2/29
A variety of low-density parity-check (LDPC) ensembles have now been observed to approach capacity with message-passing decoding. However, all of them use soft (i.e., non-binary) messages and a poster...
Closed Form Secrecy Capacity of MIMO Wiretap Channels with Two Transmit Antennas
Secrecy capacity MIMO wiretap channel physical layer security
2011/9/22
Abstract: A Gaussian multiple-input multiple-output (MIMO) wiretap channel model is considered. The input is a two-antenna transmitter, while the outputs are the legitimate receiver and an eavesdroppe...
Effective Capacity of Two-Hop Wireless Communication Systems
Two-hop wireless links fading channels effective capacity quality of service (QoS) constraints buffer violation probability
2011/9/16
Abstract: A two-hop wireless communication link in which a source sends data to a destination with the aid of an intermediate relay node is studied. It is assumed that there is no direct link between ...
