"At OFC 2018, Keysight will demonstrate test solutions for 100G, 400G, 600G, and 1-Tb/s transmission--that includes both
coherent signal forms such as QAM64 and noncoherent signal forms such as PAM4.
It is noteworthy that topics and approaches handled in this issue can be extended further to research on diverse issues, such as advanced covert communication systems, secure communications in hostile environments, countermeasures against covert communication network, system performance modeling and simulation in hostile environments, reliability and survivability for susceptible networks, emerging surveillance techniques using active and passive sensing, advanced networked and agile systems for hostile environments, cooperation-based systems, and cognitive radio networks operating in hostile environments distributed and
coherent signal processing for physical security communications, and emerging manned and unmanned covert applications for air, sea, land, and space.
"The key here is that after you look across all of [the datasets], you see a
coherent signal," he says.
One is that it can process
coherent signal; the other is that it can complete DOA estimation in few snapshots.
With best-in-class features and performance for complex Electronic Warfare (EW), Electronic Intelligence (ELINT) and radar applications, the transceiver provides excellent multichannel, high-resolution, synchronized and
coherent signal processing.
A component used for
coherent signal demodulation for either heterodyne or intradyne detections.
If N is the number of stations in the array, the linear summation yields improvement of the signal-to-noise ratio by the factor [square root of N], assuming the absolutely
coherent signal and absolutely non-coherent noise.
