My name is Klaus Boje von der Heide.
Klaus and Boje are first names and von der Heide is the family name. I explicitely say that because I gathered a large and funny collection of letters naming me Mrs. Dr. Heide von der Klaus or simply Sehr geehrter Herr Dr. von, .

Some Personal Data

Born in 1941. Radio Amateur License since 1959.
I studied Physics, Mathematics and Astronomy at the University Hamburg.

Current Position

Professor of Computer Science at the University Hamburg
in the Department Technical Computer Science

Teaching Area

Basic Courses in Computer Science,
Advanced Courses in Computer Architecture, Digital Signal Processing, Chip Design.
Some Course Material is based on MATLAB and is available on request (look at Download).

Scientific Area

Computer Architecture, Digital Signal Processing, Fault Tolerance

Personal Interests

Digital Communication in Amateur Radio, Coding Theory and the whole world of nature. Pactor1/2 is my favorite mode on HF, CW, SSB, FSK441 and JT65B on VHF. But mostly I am simulating new modes on the computer. So DJ5HG is rare on the bands.
