Effective Secrecy: Reliability, Confusion and Stealth
Jie Hou, Gerhard Kramer
A security measure called effective security is defined that includes strong secrecy and stealth communication. Effective secrecy ensures that a message cannot be deciphered and th…
Short Message Noisy Network Coding with a Decode-Forward Option
Jie Hou, Gerhard Kramer
Short message noisy network coding (SNNC) differs from long message noisy network coding (LNNC) in that one transmits many short messages in blocks rather than using one long messa…
Multi-sample Receivers Increase Information Rates for Wiener Phase Noise Channels
Hassan Ghozlan, Gerhard Kramer
A waveform channel is considered where the transmitted signal is corrupted by Wiener phase noise and additive white Gaussian noise (AWGN). A discrete-time channel model is introduc…
Feasibility Conditions of Interference Alignment via Two Orthogonal Subcarriers
Stefan Dierks, Gerhard Kramer, Wolfgang Zirwas
Conditions are derived on line-of-sight channels to ensure the feasibility of interference alignment. The conditions involve choosing only the spacing between two subcarriers of an…
Informational Divergence Approximations to Product Distributions
Jie Hou, Gerhard Kramer
The minimum rate needed to accurately approximate a product distribution based on an unnormalized informational divergence is shown to be a mutual information. This result subsumes…
On Wiener Phase Noise Channels at High Signal-to-Noise Ratio
Hassan Ghozlan, Gerhard Kramer
Consider a waveform channel where the transmitted signal is corrupted by Wiener phase noise and additive white Gaussian noise (AWGN). A discrete-time channel model that takes into…
