On Multi-User Deep-Learning-Based Non-Coherent DPSK Multiple-Symbol Differential Detection in Massive MIMO Systems

IEEE Access, 2021
In view of reducing the complexity of signal detection in massive multiple-input multiple-output (MIMO) receivers, the use of non-coherent detection is favored over usual coherent techniques that require complex channel estimation.

Coherent Measurements of a Multistatic MIMO Radar Network With Phase Noise Optimized Non-Coherent Signal Synthesis

IEEE Journal of Microwaves, 2022
For multistatic radar networks in the upper mm-wave range with a large spacing between its radar sensor nodes, a coherent signal distribution is very complex and thus very costly.

CPFSK Signal Detection in White and Bursty Impulsive Noises

IEEE Access, 2019
Designing communication techniques for non-Gaussian impulsive noise has been attracting considerable attention from the research community. In this paper, we focus on the continuous phase frequency shift keying (CPFSK) signal detection for both white and

Airborne FDA-MIMO Radar Modeling and Detection Performance Analysis [PDF]

Radioengineering, 2021
In the conventional frequency diverse array (FDA) radar designs, generalized likelihood ratio test (GLRT) detection utilizes coherent pulses. However, the impacts of an FDA multiple-input multiple-output (FDA-MIMO) radar system for detection with ...

DLI-Based DP-QPSK Reception Scheme for Short-Range Optical Communication

Applied Sciences, 2020
The unacceptably high cost of digital coherent receivers for short-range optical communication has in recent years fueled the study of alternative transmission schemes that are simultaneously highly performing and cost-effective.

Power-Bandwidth Tradeoff for Ultra-Low Power MFSK and G-MFSK Systems

IEEE Access, 2023
In one of our previous papers, we designed an ultra-low power non-coherent MFSK system using 2-pole bandpass filters to replace matched filters for detection and showed the performance loss between our proposed system and the optimal MFSK system using ...

Tracking Small Wildlife With Minimal-Complexity Radio Frequency Transmitters: Near-Optimal Detection

IEEE Access, 2023
In a range of IoT applications, edge nodes require minimal size, mass, and power/energy use. When node complexity is severely constrained, the burden of detection falls to the receiving system.
