Improved Lower Bounds on the Capacity of the Binary Deletion Channel via a Learning Approach to Run-Length Inputs
Hassan Khodaiemehr, Chen Feng, Tolga M. Duman
The best constructive lower bounds on the capacity of the binary deletion channel come from random codes with independent run lengths, yet the two strongest such bounds, due to Dri…
Full-Diversity Construction-D Lattices: Design and Decoding Perspective on Block-Fading Channels
Maryam Sadeghi, Hassan Khodaiemehr, Chen Feng
This paper introduces a novel framework for constructing algebraic lattices based on Construction-D, leveraging nested linear codes and prime ideals from algebraic number fields. W…
Blockchain Security Risk Assessment in Quantum Era, Migration Strategies and Proactive Defense
Yaser Baseri, Abdelhakim Hafid, Yahya Shahsavari +2
The emergence of quantum computing presents a formidable challenge to the security of blockchain systems. Traditional cryptographic algorithms, foundational to digital signatures,…
Design and Practical Decoding of Full-Diversity Construction A Lattices for Block-Fading Channels
Hassan Khodaiemehr, Daniel Panario, Mohammad-Reza Sadeghi
Block-fading channel (BF) is a useful model for various wireless communication channels in both indoor and outdoor environments. The design of lattices for BF channels offers a cha…
Construction and Encoding of QC-LDPC Codes Using Group Rings
Hassan Khodaiemehr, Dariush Kiani
Quasi-cyclic (QC) low-density parity-check (LDPC) codes which are known as QC-LDPC codes, have many applications due to their simple encoding implementation by means of cyclic shif…
Construction of Full-Diversity LDPC Lattices for Block-Fading Channels
Hassan Khodaiemehr, Mohammad-Reza Sadeghi, Daniel Panario
LDPC lattices were the first family of lattices which have an efficient decoding algorithm in high dimensions over an AWGN channel. Considering Construction D' of lattices with one…
LDPC Lattice Codes for Full-Duplex Relay Channels
Hassan Khodaiemehr, Dariush Kiani, Mohammad-Reza Sadeghi
Low density parity check (LDPC) lattices are obtained from Construction D' and a family of nested binary LDPC codes. We consider an special case of these lattices with one binary L…
Practical Encoder and Decoder for Power Constrained QC-LDPC lattices
Hassan Khodaiemehr, Mohammad-Reza Sadeghi, Amin Sakzad
LDPC lattices were the first family of lattices that equipped with iterative decoding algorithms under which they perform very well in high dimensions. In this paper, we introduce…
