Channel capacities of fading radio channels
Proceedings of PIMRC '96 - 7th International Symposium on Personal, Indoor, and Mobile Communications, 2002Channel capacities of various channel models are investigated. We consider two frequency selective channels, the indoor radio channel, simulated with ray tracing, and the two path channel. Additionally Rayleigh-, Rice- and Nakagami-m-distributed stochastic channel models and the discrete-time additive Gaussian noise channel with binomial distributed ...

The channel capacity of evolution
Proceedings of the 9th annual conference on Genetic and evolutionary computation, 2007Animals and plants are intricately adapted to their environments, and much genomic information is needed to construct them. In each generation, genomic information is degraded by mutation, and it is also in some sense restored by selection. It is reasonable to ask how “information from selection” may be defined. Given a suitable definition, we may then

Mimo channel capacity measurements
2012 20th Signal Processing and Communications Applications Conference (SIU), 2012The channel capacity in the multi-antenna architecture depends not only on signal-to-noise ratio (SNR) but also the spatial correlation between antenna elements. In this study, in multi-antenna systems, measurements were made for 0.02λ receiving antenna spacing in a laboratory consisting of a full anechoic room, and the spatial correlation between far ...

1987 IEEE Symposium on Security and Privacy, 1987
Techniques for detecting covert channels are based on information flow models. This paper establishes a connection between Shannon's theory of communication and information flow models, such as the Goguen-Meseguer model, that view a reference monitor as a state-transition automaton.

On the channel capacity of wireless fading channels
Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2004The objectives of this paper are twofold. First, to point out the significance of certain results on stochastic processes in computing the channel capacity for flat fading wireless channels. Next, to design an optimal encoding and decoding strategies for general sources, when the channel is perfectly known to both transmitter and receiver.

IEEE Communications Letters, 2011
Alpha-stable distributions have found various applications in the literature especially in modelling impulsive noise in communications channels. Despite various schemes for receiver design under alpha-stable noise, the channel coding problem has not been addressed yet.

Asymptotic capacity of a random channel
2014 52nd Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2014We consider discrete memoryless channels with input and output alphabet size n whose channel transition matrix consists of entries that are independent and identically distributed according to some probability distribution v on (R≥0, B(R≥0)) before being normalized, where v is such that E[X log X)2 1 1 := E[X] and μ 2 := E[X log X] for a random ...

The Capacity of a Possibilistic Channel
2001We put forward a model for transmission channels and channel coding which is possibilistic rather than probabilistic. We define a notion of possibilistic capacity, which is connected to a combinatorial notion called graph capacity. In the probabilistic case graph capacity is a relevant quantity only when the allowed decoding error probability is ...

Bounds on the capacity of the unidirectional channels
IEEE Transactions on Computers, 2005In the usual binary symmetric channel, both 1/spl rarr/0 and 0/spl rarr/1 types of errors can occur. In the binary asymmetric channel, only 1/spl rarr/0 type of errors can occur, whereas, in the unidirectional channel, both 1/spl rarr/0 and 0/spl rarr/1 types of errors can occur, but, unlike the binary symmetric channel, for any particular transmitted ...

The Capacity of the Gaussian Channel with Feedback
Bell System Technical Journal, 1970In this paper we provide a rigorous proof that feedback cannot increase the capacity of the channel with additive colored gaussian noise by more than a factor of two. We also give a tighter bound showing that any increase in capacity is less than the normalized correlation between the signal and noise.
