Multi-Story Building Model for Efficient IoT Network Design
Mathematics, 2023 This article presents a new network model for IoT that is based on a multi-story building structure. The model locates network nodes in a regular, cubic lattice-like structure, resulting in an equation for the signal-to-noise ratio (SNR).

Error Exponents of LDPC Codes under Low-Complexity Decoding
Entropy, 2021 This paper deals with the specific construction of binary low-density parity-check (LDPC) codes. We derive lower bounds on the error exponents for these codes transmitted over the memoryless binary symmetric channel (BSC) for both the well-known maximum ...
