Therefore, blind channel estimation is an alternative way to avoid pilot transmission. Considering a time-varying channel and taking the advantages of machine learning techniques, blind
In the detection range of Doppler radar, once the relative range rate of the target is less than the minimum detectable velocity (MDV), it means that the target enters the Doppler blind zone (DBZ) of
To determine the power budget and power margin needed for fiber-optic connections, you need to understand how signal loss, attenuation, and dispersion affect transmission. The uses
Two network topologies were chosen for the study, representing the different characteristics of a national (Nobel-Germany) and a continen-tal (Nobel-EU) backbone network.
Application note: Practical overview of optical loss testing theory and practice for fiber optic communication systems.
Implemented by this multi-task deep network, the designed MW-Net can predict the illumination information to obtain interferograms at two different wavelengths from interferogram at a
Blind modulation classification (MC) is an integral part of designing an adaptive or intelligent transceiver for future wireless communications. Blind MC
In 9, a novel solution for robust continuous-time beam tracking leveraging a liquid neural network was proposed, dynamically adjusting the narrow millimeter-wave beams to ensure real-time
Here, we look at minimizing the effect of blind ranges by varying the radar pulse-repetition frequency (PRF) and interpolating across the gaps to preserve azimuth
In systems based on dispersion compensating fiber, micro-ring resonator array, and Mach-Zehnder interferometer array that use multi-wavelength optical carriers as the light source, the...
This document describes how to calculate the maximum attenuation for an optical fiber. You can apply this methodology to all types of optical fibers in
Light traversing a medium may be attenuated by absorption (Fig. 1), scattering (Fig. 2, Fig. 3), or both. In a medium, which contains both light
WDM is a technique that transmits multiple light signals of different wavelengths over a single fiber strand. By assigning each signal a distinct
We in-vestigate the performance for different specifications as compared to single-wavelength transponders in a network planning study on two network topologies, developing guidelines for multi
The backbone optical fiber cabling link segment shall be tested in at least one direction at both operating wavelengths to account for attenuation deltas associated with wavelength.
We propose blind estimators for the average noise power, receive signal power, signal-to-noise ratio (SNR), and mean-square error (MSE), suitable for multi-ante
In wireless communications, the channel characteristics depend largely on multiple factors, e.g., the type of air-interface design, the used radio spectrum, and the network architecture. The

In this letter, we investigate the blindness compensation for millimeter wave (mmWave) wireless networks by appropriately deploying the reconfigurable intelligent surface (RIS). Specifically,
This work addresses a novel method of eliminating blind zones in radar detection systems based on a combined use of a waveform design and a coherent filter design.
In fiber optic communication, attenuation refers to the loss of signal strength as light travels through the optical fiber. This signal loss is inevitable and
