The main contribution is the representation of a sparse channel model and the exploitation of a modified approach based on Multiple Measurement Vector (MMV) greedy sparse framework and subspace method of Multiple Signal Classification (MUSIC) which work together to recover the indices of non-zero elements of an unknown channel matrix when the rank of the channel matrix is defected.
The forward operator H is created from the concatenation of all the individual source-detector measurement expressions and encapsulates both the forward model projection from the volume underneath the optical probe to the set of measurement channels and the modified Beer-Lambert relationship (conversion of hemoglobin changes to absorption changes at multiple wavelengths).
Furthermore, a natural extension of single measurement vector is the joint sparse recovery problem, also known as the multiple measurement vector (MMV) problem, which arises naturally in source localization [3], neuromagnetic imaging [5], and equalization of sparse-communication channels [6].
The multiple measurements are transmitted to the remote filter via distinct communication channels, and each measurement loss process is described by a two-state Markov chain.
Multiple data packet dropouts occur randomly in both control channel and measurement channel.
Following this, noise estimates from multiple signals are partitioned into bins based on a variable that correlates with the noise amplitude, such as measurement channel or signal intensity.
The connection between multiple measurements isn't conclusive, she hastens to add.
Multiple measurements may have better prediction power.
The use of dark Mylar on the sample flowcell greatly reduces adhesive-derived scattering of the excitation light, allowing for the simultaneous measurement of multiple independent channels on the same flowcell.
Using microscopes with multiple detection channels, a measurement generates a set of auto- and cross-correlation curves, which contains information about dynamic molecular processes associated with the fluorescence emission from a femtoliter-sized detection volume (Schwille, 2001).
