A new publication from Opto-Electronic Advances, 10.29026/oea.2023.220157 discusses lensless complex amplitude demodulation based on deep learning in holographic data storage. In the era of big data, ...

As a next-generation optical archive storage device for 8K video, we have been researching and developing holographic memory. Recent studies have focused on multi-level code instead of binary code to ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

Signal modulation is one of the most basic and important concepts in the RF industry. It consists of using the variation of one or more parameters of a carrier signal to transmit information, ...
