Full Brain Blood-Oxygen-Level-Dependent Signal Parameter Estimation Using Particle Filters
… By using a particle filter to optimize the model parameters, the computation time is kept below a minute per voxel without requiring a linearization of the noise in the state variables. The activation results show regions similar to those found in Statistical Parametric Mapping; however, there are …

Spectrum Sensing in the Presence of Channel and Tx/Rx Impairments
… of spectrum sensing, defined here to consist of signal detection, signal parameter estimation, and signal identification, is a critically important task in a wide-variety of wireless communication applications. For example, in recent years, government and research initiatives have proposed the …

Coherent Mitigation of Radio Frequency Interference in 10-100 MHz
… resulting in no distortion of the underlying signals. This approach is of interest in weak signal applications such as radio astronomy, where the signal of interest may have interference-to-noise ratio much less than one, and so can be easily distorted by other methods. Environmental noise in …
