Capacity and Normalized Optimal Detection Error in Gaussian Channels
Edwin Hammerich
For vector Gaussian channels, a precise differential connection between channel capacity and a quantity termed normalized optimal detection error (NODE) is presented. Then, this C-…
Waterfilling Theorems for Linear Time-Varying Channels and Related Nonstationary Sources
Edwin Hammerich
The capacity of the linear time-varying (LTV) channel, a continuous-time LTV filter with additive white Gaussian noise, is characterized by waterfilling in the time-frequency plane…
Waterfilling Theorems in the Time-Frequency Plane for the Heat Channel and a Related Source
Edwin Hammerich
The capacity of the heat channel, a linear time-varying (LTV) filter with additive white Gaussian noise (AWGN), is characterized by waterfilling in the time-frequency plane. Simila…
Correction to "A Note on Gallager's Capacity Theorem for Waveform Channels"
Edwin Hammerich
We correct an alleged contradiction to Gallager's capacity theorem for waveform channels as presented in a poster at the 2012 IEEE International Symposium on Information Theory.
On the Capacity of the Heat Channel, Waterfilling in the Time-Frequency Plane, and a C-NODE Relationship
Edwin Hammerich
The heat channel is defined by a linear time-varying (LTV) filter with additive white Gaussian noise (AWGN) at the filter output. The continuous-time LTV filter is related to the h…
Design of Pulse Shapes Based on Sampling with Gaussian Prefilter
Edwin Hammerich
Two new pulse shapes for communications are presented. The first pulse shape generates a set of pulses without intersymbol interference (ISI) or ISI-free for short. In the neighbor…
A Generalized Sampling Theorem for Frequency Localized Signals
Edwin Hammerich
A generalized sampling theorem for frequency localized signals is presented. The generalization in the proposed model of sampling is twofold: (1) It applies to various prefilters e…
