579. LPT: Linear Predictive Single Value Decomposition of
Decaying Sinusoids for Spectral Analysis in NMR
by David Cowburn and Jewel Chaudhary, The Rockefeller
University, New York, New York 10021
This program is used for the determination of a complex
time-domain signal as the summation of a number of
exponentially damped sinusoids.
The frequencies and damping factors are determined via
linear prediction. The linear prediction equations are
solved with a linear least-squares procedure via
diagonalization of the "normal equations" (indirect
singular value decomposition). The frequencies and
damping factors are determined by polynomial
factorization. The amplitude and phases are obtained
by a second linear least-squares procedure.
There are two versions of this program, each containing
a different driver. Both drivers expect an input data
file of double complex data. One version requests the
needed parameters which the user supplies, while the
other version expects the parameters to be entered in a
parameter file.
