Sensitivity Deterioration of Free-Space Optical Coherent/Non-Coherent OOK Modulation Receiver by Ambient Light Noise [PDF]
Sensors, 2023 In free-space optical (FSO) communication systems, on–off keying (OOK) is a widely used modulation format. Coherent and non-coherent OOK receivers with sensitivities of −54.60 dBm and −51.25 dBm, respectively, were built with a communication rate of 1 ...

An Enhanced Non-Coherent Pre-Filter Design for Tracking Error Estimation in GNSS Receivers [PDF]
Sensors, 2017 Tracking error estimation is of great importance in global navigation satellite system (GNSS) receivers. Any inaccurate estimation for tracking error will decrease the signal tracking ability of signal tracking loops and the accuracies of position fixing,

Polar-Coded Non-Coherent Communication [PDF]
IEEE Communications Letters, 2021 A polar-coded transmission (PCT) scheme with joint channel estimation and decoding is proposed for channels with unknown channel state information (CSI). The CSI is estimated via successive cancellation (SC) decoding and the constraints imposed by the frozen bits.

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.

Non-coherence in estimation and control [PDF]
2013 51st Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2013 Control strategies for systems with information bottlenecks often follow an estimate-then-control paradigm. This paper presents a “non-coherent” system where this strategy cannot work and provides an alternative. The paper considers the estimation and control of a discrete-time linear system with continuous random observation gain, i.e.

Learning to Modulate for Non-coherent MIMO [PDF]
ICC 2020 - 2020 IEEE International Conference on Communications (ICC), 2020 The deep learning trend has recently impacted a variety of fields, including communication systems, where various approaches have explored the application of neural networks in place of traditional designs. Neural networks flexibly allow for data/simulation-driven optimization, but are often employed as black boxes detached from direct application of ...

Differential Data-Aided Channel Estimation for Up-Link Massive SIMO-OFDM
IEEE Open Journal of the Communications Society, 2020 Pilot symbol assisted modulation (PSAM) is widely used to obtain the channel state information (CSI) needed for coherent demodulation. It allows the density of pilot symbols to be dynamically chosen depending on the channel conditions.
