Strategies for Distributed Sensor Selection Using Convex Optimization
Fabian Altenbach, Steven Corroy, Georg Böcherer +1
Consider the estimation of an unknown parameter vector in a linear measurement model. Centralized sensor selection consists in selecting a set of k_s sensor measurements, from a to…
An Efficient Algorithm to Calculate BICM Capacity
Georg Böcherer, Fabian Altenbach, Alex Alvarado +2
Bit-interleaved coded modulation (BICM) is a practical approach for reliable communication over the AWGN channel in the bandwidth limited regime. For a signal point constellation w…
Short Huffman Codes Producing 1s Half of the Time
Fabian Altenbach, Georg Böcherer, Rudolf Mathar
The design of the channel part of a digital communication system (e.g., error correction, modulation) is heavily based on the assumption that the data to be transmitted forms a fai…
Writing on the Facade of RWTH ICT Cubes: Cost Constrained Geometric Huffman Coding
Georg Böcherer, Fabian Altenbach, Martina Malsbender +1
In this work, a coding technique called cost constrained Geometric Huffman coding (ccGhc) is developed. ccGhc minimizes the Kullback-Leibler distance between a dyadic probability m…
Capacity Achieving Modulation for Fixed Constellations with Average Power Constraint
Georg Böcherer, Fabian Altenbach, Rudolf Mathar
The capacity achieving probability mass function (PMF) of a finite signal constellation with an average power constraint is in most cases non-uniform. A common approach to generate…
