Comparing the paper I received from Fred and the one you can download, I see his is far more detailed and only there is the 2.4 dB improvement mentioned.
Hopefully Fred will allow me to share the full paper with you.

In looking at my copy of Dr Fred Harris' paper I was reminded that it was provided to me under NDA and so I have emailed Fred for his permission to share my copy with the group.

However a Google search led me to find his paper is already publicly available at researchgate.net<http://researchgate.net>, from where you can download it for free.  So I am under no legal or ethical limits in referring you to that site from where you can obtain his paper:


While the abstract and most of discussion focuses on the spectral and hardware efficiencies of his technique, for me the 2.4 dB improvement in noise figure mentioned in the conclusion is of greatest interest.

I will be interested to learn if this has any relevance to our project.
