1. Hilbert-Huang Transform Data Processing System (HHT-DPS) V1.2
A scientific and engineering analysis tool for non-linear and non-stationary data applications
by Semion Kizhner, Karin Blank, Tom Flatley / 560,
Dr. Norden E. Huang / 971, and Darrell Smith / OSC 1

2. Phase 1 – “Software Only” version
Goals and Objectives
Design and build a turn-key, user-friendly, file driven, PC based system that implements the HHT algorithms developed by Dr. Norden Huang
Phase 1 – “Software Only” version
Phase 2 – “Hardware Accelerated” version 2

4. Intrinsic Mode Functions4

5. HHT Application Example5

6. Development Strategy
Use Dr. Huang’s published papers and NASA patented algorithms as the starting point
Port, analyze and re-use only the “available and proven HHT source code fragments” and Matlab scripts
Use existing Empirical Mode Decomposition executable “EMD0.exe” as a functional benchmark 6

7. Simple PC based Microsoft Windows environment
HHT-DPS Requirements
Simple PC based Microsoft Windows environment
Straightforward operation via graphical user interface
User configurable processing options
Read user data input file, generate user data output files
“Quick Look” data display capability 7

8. Development Approach
Prototype new Empirical Mode Decomposition (EMD) routines in Matlab and reproduce results from the existing “EMD0.exe”
Enhance processing algorithms in collaboration with Dr. Huang, analyze output and iterate until data is correct
Implement all prototyped algorithms (EMD and Basic Spectrum Analysis Matlab scripts) in ANSII standard ‘C’ (keeping hardware acceleration in mind) 8

9. Implementation Details
Develop user interface and system control modules
Integrate and test system modules with benchmark data set (length of day)
Document the system (official “Release V1.2” software package, code documentation, user’s guide, change request forms, problem reports, configuration management) 9
