Joint Network Lifetime Maximization and Relay Selection Design in Underwater Acoustic Sensor Networks
Z. Mohammadi, M. Soleimanpour-Moghadam, S. Talebi +1
The paper proposes a new approach to minimize the number of relays while maximizing the lifetime of underwater acoustic sensor networks (UASNs). This involves formulating the relay…
Fast Maximum-Likelihood Decoder for 4*4 Quasi-Orthogonal Space-Time Block Code
Adel Ahmadi, Siamak Talebi
This letter introduces two fast maximum-likelihood (ML) detection methods for 4*4 quasi-orthogonal space-time block code (QOSTBC). The first algorithm with a relatively simple desi…
Performance Enhancement of the Golden Code by Utilizing ORIOL Antenna
Vahid Amiri, Mohammadali Sadat Hosseini, Ali Lotfi-Rezaabad +1
In this paper, a novel method is exposed to improve the performance of the Golden code, by using octagonal reconfigurable isolated orthogonal element (ORIOL) antennas, instead of a…
Two Quasi Orthogonal Space-Time Block Codes with Better Performance and Low Complexity Decoder
Ali Lotfi-Rezaabad, Siamak Talebi, Ata Chizari
This paper presents two new space time block codes (STBCs) with quasi orthogonal structure for an open loop multi-input single-output (MISO) systems. These two codes have been desi…
Toward Smart Power Grids: Communication Network Design for Power Grids Synchronization
Hojjat Salehinejad, Farhad Pouladi, Siamak Talebi
In smart power grids, keeping the synchronicity of generators and the corresponding controls is of great importance. To do so, a simple model is employed in terms of swing equation…
