Lattice coding for Rician fading channels from Hadamard rotations
Alex Karrila, Niko R. Väisänen, David Karpuk +1
In this paper, we study lattice coding for Rician fading wireless channels. This is motivated in particular by preliminary studies suggesting the Rician fading model for millimeter…
Well-Rounded Lattices for Coset Coding in MIMO Wiretap Channels
Oliver W. Gnilke, Amaro Barreal, Alex Karrila +3
The concept of well-rounded lattices has recently found important applications in the setting of a fading single-input single-output (SISO) wiretap channel. It has been shown that,…
Well-Rounded Lattices: Towards Optimal Coset Codes for Gaussian and Fading Wiretap Channels
Mohamed Taoufiq Damir, Alex Karrila, Laia Amorós +3
The design of lattice coset codes for wiretap channels is considered. Bounds on the eavesdropper's correct decoding probability and information leakage are first revisited. From th…
Information Bounds and Flatness Factor Approximation for Fading Wiretap MIMO Channels
Amaro Barreal, Alex Karrila, David Karpuk +1
In this article, the design of secure lattice coset codes for general wireless channels with fading and Gaussian noise is studied. Recalling the eavesdropper's probability and info…
Well-Rounded Lattices for Reliability and Security in Rayleigh Fading SISO Channels
Oliver Wilhelm Gnilke, Ha Thanh Nguyen Tran, Alex Karrila +1
For many wiretap channel models asymptotically optimal coding schemes are known, but less effort has been put into actual realizations of wiretap codes for practical parameters. Bo…
A Comparison of Skewed and Orthogonal Lattices in Gaussian Wiretap Channels
Alex Karrila, Camilla Hollanti
We consider lattice coset-coded transmissions over a wiretap channel with additive white Gaussian noise (AWGN). Examining a function that can be interpreted as either the legitimat…
