BSP Toolbox

During the winter and spring terms of 2002 a capable team of four seniors (M. Aboy, C. Crespo, L. Jenkins, and J. Bassale) in the ECE department at PSU developed a suite of signal processing tools designed to help researchers rapidly perform a preliminary analysis of their data. The MATLAB toolbox posted below is the result of this effort.

• Release 1.0: BSP Toolbox (zipped)

To get started with the toolbox follow these directions.

1. Download the zip file.
2. Unzip the archive. Make sure that the files are extracted into the appropriate subdirectories. If you are using WinZip, make sure the "Use Folder Names" box is checked when you unzip the toolbox.
3. Once you start MATLAB, you need to add the toolbox to your current path. To do this you can type the following at a MATLAB prompt.
   >> addpath('C:\BSP','-end');
   >> BSPSetPath('C:\BSP');
   If you put the toolbox in a directory other than 'C:\BSP' substitute the appropriate directory name in these function arguments. Note that if you add this to a file named startup.m in the directory where MATLAB starts, the Toolbox will automatically be added to your path everytime you start MATLAB. These commands add the toolbox at the end of your MATLAB path so the toolbox will not conflict with any other toolboxes. We have tried to make sure there are no naming conflicts with any of the toolboxes sold by MathWorks.
4. Start your analysis! If you prefer to explore the toolbox first, type 'helpwin BSP'. If you extracted the toolbox in a directory with a name other than 'BSP', you will need to substitute the appropriate directory name for BSP. This command will generate MATLAB's help window with all of the toolbox documentation. You should find that this is a very helpful interface and means of getting a bird's eye view of what is contained in the toolbox.

If you use the toolbox to help generate publishable results, we ask that you cite our first paper describing the toolbox that was presented at the Biosignal 2002 conference. We plan to describe the next release of the toolbox in another paper, so please check back for an updated reference. Additional resources related to the toolbox are described below.

Presentations

• BIOSIGNAL 2002 Slides: 15-minute presentation of the toolbox given at Biosignal 2002.

Papers

• BIOSIGNAL 2002 Paper: Describes some of the toolbox functionality. Note that this paper was written before the toolbox was completed, so most, but not all, of the functionality listed in the paper actually exists in this release of the toolbox. However, there is a great deal of additional functionality that is also not listed in the toolbox.
• ICASSP 2002 Paper: Describes the PeakRestore function, a nonlinear lowpass filter that preserves peaks.
• EMBS-EMBS 2002 Paper: Describes the HarmonicPSD function, an estimate of signal power as a function of frequency for signals with semi-periodic non-sinusoidal components.

Please email and comments or bug reports to toolbox@bsp.pdx.edu. Although we worked hard to be rigorous and consistent in developing these methods, we do not guarantee that they are without bugs or that they all completely comply with the toolbox standards (Ver. 1.0).

If you would like to contribute to the toolbox, please email your functions to the same address. Note that all functions included in the next release must strictly comply with the new toolbox standards. A draft of these standards (Ver. 2.1) is included in the Documentation subdirectory. Send email if you would like the latest copy of the standards (still under development).
