Fading kitten syndrome: Factors predisposing to ‘faders’ and treatment options
Journal of Feline Medicine and Surgery, 2022 Practical relevance: Fading kitten syndrome is a condition where one or more kittens of a litter are born apparently healthy but gradually become inactive, sick and die; typically faders are considered those that die during the first 2 weeks of life.

Information bounds and flatness factor approximation for fading wiretap MIMO channels [PDF]
2016 26th International Telecommunication Networks and Applications Conference (ITNAC), 2016 In this article, the design of secure lattice coset codes for general wireless channels with fading and Gaussian noise is studied. Recalling the eavesdropper's probability and information bounds, a variant of the latter is given from which it is explicitly seen that both quantities are upper bounded by (increasing functions of) the expected flatness ...

Generic Correlation Increases Noncoherent MIMO Capacity [PDF]
, 2013 We study the high-SNR capacity of MIMO Rayleigh block-fading channels in the noncoherent setting where neither transmitter nor receiver has a priori channel state information. We show that when the number of receive antennas is sufficiently large and the

Adaptive Strong Tracking Square-Root Cubature Kalman Filter for Maneuvering Aircraft Tracking
IEEE Access, 2018 A novel strong tracking square-root cubature Kalman filter (SCKF) based on the adaptive current statistical (CS) model is proposed aiming at the maneuvering aircraft tracking problem.

Achievable Rate of Rician Large-Scale MIMO Channels with Transceiver Hardware Impairments [PDF]
, 2015 Transceiver hardware impairments (e.g., phase noise, in-phase/quadrature-phase (I/Q) imbalance, amplifier non-linearities, and quantization errors) have obvious degradation effects on the performance of wireless communications.

A novel Ricean fading channel model with random K factor
Wireless Telecommunications Symposium 2012, 2012 In this paper we develop a new model of Ricean fading channel. Instead of commonly used fading model, where only instantaneous signal to noise ratio (SNR) is assumed to be random variable, we introduce additional random variable - Ricean K factor. Probability density function (PDF) and moment generating function (MGF) of such a new distribution are ...

Strong Tracking Spherical Simplex-Radial Cubature Kalman Filter for Maneuvering Target Tracking
Sensors, 2017 Conventional spherical simplex-radial cubature Kalman filter (SSRCKF) for maneuvering target tracking may decline in accuracy and even diverge when a target makes abrupt state changes.

Design and optimization of joint iterative detection and decoding receiver for uplink polar coded SCMA system [PDF]
, 2018 SCMA and polar coding are possible candidates for 5G systems. In this paper, we firstly propose the joint iterative detection and decoding (JIDD) receiver for the uplink polar coded sparse code multiple access (PC-SCMA) system.

Covert Wireless Communications Under Quasi-Static Fading With Channel Uncertainty [PDF]
IEEE Transactions on Information Forensics and Security, 2020 Covert communications enable a transmitter to send information reliably in the presence of an adversary, who looks to detect whether the transmission took place or not.
