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.

Precoding for Non-Coherent Detection of Continuous Phase Modulations [PDF]
MILCOM 2018 - 2018 IEEE Military Communications Conference (MILCOM), 2018 Non-coherent trellis based receiver (TBR) is an effective method to demodulate noncoherent continuous-phase modulated sequences. However it requires to increase the observation length to reach the performance of classical coherent TBRs. Furthermore it appears that both receivers offers different behaviours when considered in a bit-interleaved coded ...

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 ...

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 ...

Coherent scattering and macroscopic coherence: Implications for neutrino, dark matter and axion detection [PDF]
, 2018 We study the question of whether coherent neutrino scattering can occur on macroscopic scales, leading to a significant increase of the detection cross section.

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.
