Optimal Prefix Codes for Infinite Alphabets With Nonlinear Costs
Let P = {p(i)} be a measure of strictly positive probabilities on the set of nonnegative integers. Although the countable number of inputs prevents usage of the Huffman algorithm, ...

Bounds for Codes in Products of Spaces, Grassmann, and Stiefel Manifolds
Upper bounds are derived for codes in Stiefel and Grassmann manifolds with given minimum chordal distance. They stem from upper bounds for codes in the product of unit spheres and...

Capacity of Ultra-Wideband Power-Constrained Ad Hoc Networks
In this correspondence, we show that the uniform throughput capacity of an ultra-wideband (UWB) power-constrained ad hoc network is given by 2(P ( n=logn) ), where P is the per-nod...

Signaling Over Arbitrarily Permuted Parallel Channels
The problem of transmission of information over arbitrarily permuted parallel channels is studied here. The transmitter does not know over which channel a certain codesequence will...

Approaching the Zero-Outage Capacity of MIMO-OFDM Without Instantaneous Water-Filling
Orthogonal-frequency-divisionmultiplexing(OFDM) transforms a frequency-selective multiple-input multiple-output (MIMO) fading channel into a MIMO-OFDM channel that has a well-defin...

Rate Region of the Quadratic Gaussian Two-Encoder Source-Coding Problem
We determine the rate region of the quadratic Gaussian two-encoder source-coding problem. This rate region is achieved by a simple architecture that separates the analog and digita...
