A joint encryption, channel coding and modulation scheme using QC-LDPC lattice-codes

K Bagheri, T Eghlidos, MR Sadeghi… - IEEE Transactions …, 2020 - ieeexplore.ieee.org
We propose a new nonlinear Rao-Nam like symmetric key encryption scheme. In our
design, we employ a specific type of coded modulation schemes namely quasi-cyclic low …

Secure one-way relaying scheme based on random difference family (RDF) lattice codes

K Bagheri, H Khodaiemehr, T Eghlidos, D Panario - Wireless Networks, 2021 - Springer
In this paper, we present a one-way relaying scheme in which two wireless nodes create an
information flow to each other via a single decode-and-forward (DF) relay. We consider an …
