Weak Signals and All That Kind of Stuff

[fgentges at mindspring.com]

We had a nice talk tonight at the AMRAD meeting by Frank Eliot, W3WAG.

Related are a couple of books I got some years ago that are a bit off of 
the main road.

First is "Optimum Noise Immunity" by Kotelnikov.  It is available as a 
translation from the Russian.  It looks at optimum detection of on-off 
keying type signals.  I consider it a classic that at the time was from 
behind the Iron Curtain.  A bit of math here and there but a lot of 
insight and thought processes used to solve the problem.

Second is "Transmission of Orthogonal Signals" by Henning Harmuth. This 
book is considered a classic and was written when Walsh functions were 
the hot item and this book provided insight into orthogonal Walsh 
functions but also provided insight into much more.

Both books are quite different in their approach but should provide 
useful background on weak signal detection.

Careful shopping for used versions can provide quite usable copies of 
these classics.  I found used ones listed on Amazon.  I have both here 
and am glad to loan to AMRAD members.  I will bring them to tacos on 
Saturday.

Thanks to Frank Eliot for stimulating member's interest in this subject.
