Advanced Noncoherent Detection in Massive MIMO Systems via Digital Beamspace Preprocessing
Telecom, 2020 Noncoherent detection in massive multiple-input/multiple-output (MIMO) uplink systems provides a low-complexity alternative to its coherent counterpart. Requiring no actual channel knowledge but the per-user induced power at the base station, comparable ...

Quantum Codes in Classical Communication: A Space-Time Block Code From Quantum Error Correction
IEEE Open Journal of the Communications Society, 2021 We propose a general framework for noncoherent communication using techniques from the field of quantum error correction (QEC). We first propose an approach for analyzing a classical communication channel as a quantum channel, and develop an extension of

A Hybrid Integration Method for Moving Target Detection With GNSS-Based Passive Radar
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Global navigation satellite system (GNSS) based passive radar has been applied in the detection of moving targets. However, the low signal power of GNSS on the earth's surface limits the application of this technology for the long-range or low-observable

CFAR Detection from Noncoherent Radar Echoes Using Bayesian Theory
EURASIP Journal on Advances in Signal Processing, 2010 We propose a new constant false alarm rate (CFAR) detection method from noncoherent radar echoes, considering heterogeneous sea clutter. It applies the Bayesian theory for adaptive estimation of the local clutter statistical distribution in the cell ...
