Fast Maximum-Likelihood Decoder for 4*4 Quasi-Orthogonal Space-Time Block Code

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 design exploits structure of quadrature amplitude modulation (QAM) constel

Performance Enhancement of the Golden Code by Utilizing ORIOL Antenna

Autor: Amiri, Vahid, Hosseini, Mohammadali Sadat, Lotfi-Rezaabad, Ali, Talebi, Siamak

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 conventional microstrip patch antenna. The aforementioned antenna, sh

Two Quasi Orthogonal Space-Time Block Codes with Better Performance and Low Complexity Decoder

Autor: Lotfi-Rezaabad, Ali, Talebi, Siamak, Chizari, Ata

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 designed to transmit from three or four antennas at the transmitter and be

Toward Smart Power Grids: Communication Network Design for Power Grids Synchronization

Autor: Salehinejad, Hojjat, Pouladi, Farhad, Talebi, Siamak

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 to represent the interactions among dynamics of generators and feedba
