Corix

Welcome to my home page. My name is Jens J°rgen Nielsen, but as my hobby projects are sort of semi-professional I decided to present them on this site. 

Corix is also the name of a small company I own. It provides consultancy and solutions in areas such as signal processing, coding and cryptography. 

What's here?

Various stuff I made over the years:

>

The C-source for an arbitrary N Fast Fourier Transform (FFT)

>

An idea for quantization of FIR filters

>

Encoders/decoders for of various Error Correcting Codes (ECC)

>

A tiny Windows game

>

An extension for Sketchup that draws the M÷bius strip and (much) more


What's new?

November 2012: C source for Hamming & Golay codes available.
November 2012: C source for Reed-Solomon codes available.
