A paper about a refined multitaper spectral analysis. We estimate the derivatives of the power spectra to better describe to frequency content of the signals.

Recently accepted in Computers & Geosciences, this paper is about a set of codes for spectral analysis, coherences, transfer func tion estimation and decon volution using different multi taper methods.

The Multitaper Spectrum Estimation Library mwlib.a is a Fortran 90 Library containing different subroutines to estimate the Power Spectral Density of real time series. Due to limitations in the free Fortran 90 compiler G95, it is not yet possible to compile this library with the free version. Please keep checking, since whenever this becomes possible, I will update.

The paper has recently been accepted in Computers & Geosciences. A preprint is available in the Publications section. The new release has a set of simple codes to reproduce the figures in the paper.

If you have any comments about this library, or would like to suggest any improvements in the presentation, download, documentation, etc, please let me know.

How do I compile the library?
How about documentation?
Where do I download the source code?

How do I compile the Library?

The first thing you need to do, is of course download the source code (below) and have a F90 compiler (the free compiler G95 NOW does work with this code) available.

Download, unzip and untar the file into a given directory, which we will call ~/mtspec/

Simply look for the appropriate Makefile in the makefiles/ folder and type make. In most cases there is no need to edit anything. Some test programs to replicate the figures in the paper are available at ~/mtspec/examples. The Makefile compiles this programs as well.

How about documentation?

The documentation is now up to date. mtspec.pdf, programs.pdf

New Updates

May 2005

I added capabilities to input/output single precision data. Also, I added estimation of dual-frequency coherence. Documentation is not ready, but there is an example to start with.

February 2008

I recently submitted a paper about this library to Computers & Geosciences. The new release has a set of simple codes to reproduce the figures in the paper.

April 2008

Revised version of the codes. Thanks to anonymous reviewers for comments. The new release has new interactive programs to play with the different parameters and methods. The user does not need to know any Fortran to run this programs.

Compatible with G95, gfortran, and other compilers in Mac, Linux and Sun computers.
