Spread Spectrum Scene
Pseudo-Noise (PN) Codes
PN codes are the very heart of EVERY Spread Spectrum system. To
design, build or understand a Spread Spectrum system requires a working knowledge of and a thorough
insight into these somewhat "mystical" codes. This page provides links to PN Code
information, theory, implementation and practice.

PN Code Information on the Web
by R. A. Axford, Jr., L. B. Milstein, and J. R. Zeidler, 1998 paper in IEEE Transactions
June 2001 paper from
NASA's Jet Propulsion Laboratory, Pasadena, California
. The link leads you to a page where you can download the pdf. The first couple of pages are in Dutch, but by
the time you get to the thesis itself it is in English.
