Word-Valued Sources: an Ergodic Theorem, an AEP and the Conservation of Entropy
Roy Timo, Kim Blackmore, Leif Hanlen
A word-valued source is discrete random process that is formed by sequentially encoding the symbols of a random process with c…
Space-Time-Frequency Degrees of Freedom: Fundamental Limits for Spatial Information
Leif Hanlen Thushara Abhayapala
We bound the number of electromagnetic signals which may be observed over a frequency range a time interval within a sphere of radius . We show that the such…
Bounds on Space-Time-Frequency Dimensionality
Leif Hanlen, Thushara Abhayapala
We bound the number of electromagnetic signals which may be observed over a frequency range for a time within a region of space enclosed by a radius . Our result implie…
Uncertainty Principles for Signal Concentrations
Ram Somaraju, Leif W. Hanlen
Uncertainty principles for concentration of signals into truncated subspaces are considered. The ``classic'' uncertainty principle is explored as a special case of a more general o…
Optimal Transmit Covariance for Ergodic MIMO Channels
Leif W Hanlen, Alex J Grant
In this paper we consider the computation of channel capacity for ergodic multiple-input multiple-output channels with additive white Gaussian noise. Two scenarios are considered.…
