Quantized Precoding for Multi-Antenna Downlink Channels with MAGIQ
Andrei Nedelcu, Fabian Steiner, Markus Staudacher +5
A multi-antenna, greedy, iterative, and quantized (MAGIQ) precoding algorithm is proposed for downlink channels. MAGIQ allows a straightforward integration with orthogonal frequenc…
Coding for Positive Rate in the Source Model Key Agreement Problem
Amin Gohari, Onur Günlü, Gerhard Kramer
A two-party key agreement problem with public discussion, known as the source model problem, is considered. By relating key agreement to hypothesis testing, a new coding scheme is…
Code Constructions for Physical Unclonable Functions and Biometric Secrecy Systems
Onur Günlü, Onurcan İşcan, Vladimir Sidorenko +1
The two-terminal key agreement problem with biometric or physical identifiers is considered. Two linear code constructions based on Wyner-Ziv coding are developed. The first constr…
Energy Conservation in Optical Fibers with Distributed Brick-Walls Filters
Javier Garcia, Hassan Ghozlan, Gerhard Kramer
A band-pass filtering scheme is proposed to mitigate spectral broadening and channel coupling in the Nonlinear Schrödinger (NLS) fiber optic channel. The scheme is modeled by modif…
Autocorrelation Function for Dispersion-Free Fiber Channels with Distributed Amplification
Gerhard Kramer
Optical fiber signals with high power exhibit spectral broadening that seems to limit capacity. To study spectral broadening, the autocorrelation function of the output signal give…
Capacity Bounds on the Downlink of Symmetric, Multi-Relay, Single Receiver C-RAN Networks
Shirin Saeedi Bidokhti, Gerhard Kramer, Shlomo Shamai
The downlink of symmetric Cloud Radio Access Networks (C-RANs) with multiple relays and a single receiver is studied. Lower and upper bounds are derived on the capacity. The lower…
