Greedy reconstruction algorithm for the identification of spin distribution
نویسندگان
چکیده
We propose a greedy reconstruction algorithm to find the probability distribution of parameter characterizing an inhomogeneous spin ensemble in Nuclear Magnetic Resonace. The identification is based on application number constant control processes during given time for which final magnetization vector measured. From these experimental data, we show that identifiability piecewise approximation related invertibility matrix depends different protocols applied system. aims design specific controls ensure this as far possible from singular matrix. Numerical simulations reveal efficiency examples. A systematic comparison with respect random pulses done.

15 صفحه اولSparse Signals Reconstruction via Adaptive Iterative Greedy Algorithm
Compressive sensing(CS) is an emerging research field that has applications in signal processing, error correction, medical imaging, seismology, and many more other areas. CS promises to efficiently reconstruct a sparse signal vector via a much smaller number of linear measurements than its dimension. In order to improve CS reconstruction performance, this paper present a novel reconstruction g...
