Cross‐Attractor Transforms: Improving Forecasts by Learning Optimal Maps Between Dynamical Systems and Imperfect Models [PDF]
Geophysical Research LettersBiased, incomplete numerical models are often used for forecasting states of complex dynamical systems by mapping an estimate of a “true” initial state into model phase space, making a forecast, and then mapping back to the “true” space.

A Novel Direction-of-Arrival Estimation via Phase Retrieval with Unknown Sensor Gain-and-Phase Errors [PDF]
Sensors, 2019 In signal array processing, high-resolution direction-of-arrival (DOA) estimation algorithms work well on the assumption that the system models are perfect. However, in practicality, there are imperfect system models in which sensor gain-and-phase errors

Performance of turbo coded signals over partial response fading channels with imperfect phase reference [PDF]
, 2021 In this paper, the performance of turbo coded signals are investigated over a new channel model, denoted as 1 +/- D-n / Partial Response Fading Channels (PRFC) with imperfect phase reference.

Bayesian meta‐analysis of diagnostic tests allowing for imperfect reference standards [PDF]
, 2013 There is an increasing interest in meta-analyses of rapid diagnostic tests (RDTs) for infectious diseases. To avoid spectrum bias, these meta-analyses should focus on phase IV studies performed in the target population.

Phase Noise Effects and Mitigation Techniques [PDF]
, 2020 The effect of phase noise in 5G is very relevant. With OFDM, correction schemes can combine phase noise reduction and channel estimation. In 5G, the use of multiple‐input‐multiple output requires the extension to MIMO‐OFDM, in particular using zero ...

Phase Noise Model for Continuous-Variable Quantum Key Distribution Using a Local Local Oscillator [PDF]
, 2021 The value of residual phase noise, after phase compensation, is one of the key limitations of performance improvement for continuous-variable quantum key distribution using a local local oscillator (LLO CV-QKD) system, since it is the major excess noise.
