Smart Self-Coherent Optical Communication for Short Distances
Frontiers in Communications and Networks, 2022 We proposed and investigated a high-performance, energy-efficient, and low-cost self-homodyne coherent detection transmission (SHCDT) system for the 5G access network segment assuring high capacity and light digital signal processing (DSP) at the same ...

Coherent Optical Communications
The Review of Laser Engineering, 1985 Coherent optical communication systems became possible with development of the gas laser in the early 1960s. During the decade following development of the laser, Enloe and Rodda showed homodyne detection to be possible when they successfully phase-locked two gas lasers.

Binary Communication with Gazeau–Klauder Coherent States
Entropy, 2020 We investigate advantages and disadvantages of using Gazeau−Klauder coherent states for optical communication. In this short paper we show that using an alphabet consisting of coherent Gazeau−Klauder states related to a Kerr-type nonlinear ...

Sensors, 2023 In free-space optical (FSO) communication systems, on–off keying (OOK) is a widely used modulation format. Coherent and non-coherent OOK receivers with sensitivities of −54.60 dBm and −51.25 dBm, respectively, were built with a communication rate of 1 ...

Non-Orthogonality Measure for a Collection of Pure Quantum States
Entropy, 2022 Modern optical communication technology can realize a large-scale multilevel (or M-ary) optical signal. Investigating the quantum mechanical nature of such a large-scale M-ary optical signal is essential for a unified understanding of quantum information

Coherent optical communications enhanced by machine intelligence
Machine Learning: Science and Technology, 2020 Abstract Accuracy in discriminating between different received coherent signals is integral to the operation of many free-space communications protocols, and is often difficult when the receiver measures a weak signal. Here we design an optical communication scheme that uses balanced homodyne detection in combination with an unsupervised

Comparison between Direct and Coherent Optical Communication System
مجلة بغداد للعلوم, 2011 The work in this paper focuses on the system quality of direct and coherent communication system for two computers. A system quality is represented by Signal to Noise ratio (SNR) and Bit Error Rate (BER).
