Statistical Studies of Fading in Underwater Wireless Optical Channels in the Presence of Air Bubble, Temperature, and Salinity Random Variations (Long Version)
Mohammad Vahid Jamali, Ali Mirani, Alireza Parsay +6
Optical signal propagation through underwater channels is affected by three main degrading phenomena, namely absorption, scattering, and fading. In this paper, we experimentally st…
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…
Mining DNA Sequences Based on Spatially Coded Technique Using Spatial Light Modulator
Masoome Fazelian, Sajjad AbdollahRamezani, Sima Bahrani +6
In this paper, we present an optical computing method for string data alignment applicable to genome information analysis. By applying moire technique to spatial encoding patterns…
Statistical Distribution of Intensity Fluctuations for Underwater Wireless Optical Channels in the Presence of Air Bubbles
Mohammad Vahid Jamali, Pirazh Khorramshahi, Arvin Tashakori +6
In this paper, we experimentally investigate the statistical distribution of intensity fluctuations for underwater wireless optical channels under different channel conditions, nam…
Performance Analysis of Multi-Hop Underwater Wireless Optical Communication Systems (Extended Version)
Mohammad Vahid Jamali, Ata Chizari, Jawad A. Salehi
In this paper, we evaluate the end-to-end bit error rate (BER) of point-to-point underwater wireless optical communication (UWOC) systems with multi-hop transmission. To do so, we…
Designing A Dimmable OPPM-Based VLC System Under Channel Constraints
Ata Chizari, Mohammad Vahid Jamali, Jawad A. Salehi +1
In this paper, we design a dimming compatible visible light communication (VLC) system in a standard office room according to illumination standards under channel constraints. We u…
