Nick VA3NNW's KWARC CDMA talk

In Jan 2010, I gave a talk to KWARC about CDMA - Code Division Multiple Access.

The talk is © Copyright 2010 "Nosey" Nick Waterman VA3NNW but is free for radio hams to present to other radio hams. Please let me know if you DO use it for this purpose (because I'm nosey and like to know who uses my stuff), or please ask my permission if you wish to use it for any other purpose (because that's the point of the copyright).

It can be downloaded here:

CDMA.odp (0.7MB OpenOffice Presentation) - the actual presentation
CDMA.ppt (1.7MB Micro$oft Office PowerPoint) - but seriously, look at the file size, who still uses M$ Office?!?
CDMA_WS.ods (49KB OpenOffice Spreadsheet) - the worksheets used by each side of the room to "transmit" CDMA to be "received" by the other side of the room. Also contains a sheet of graphs, and has a few hidden calculations if you want to play with CDMA signals yourself.
CDMA_WS.xls (68KB Micro$oft Excel Spreadsheet) - but seriously, see above

Some other files I used to make the presentation

You're unlikely to want these unless you wanted to rewrite the presentation yourself, but they can be downloaded subject to the same copyright as above

CDMA1.ods - another spreadsheet to play with CDMA
CDMA2.ods - another spreadsheet to play with CDMA
Makefile - runs the programs below to create some of the charts and graphs
cp.pl - to make the code plots
qso.pl - helps to make example QSOs used in ftdma2.gnuplot
cp.gnuplot fp.gnuplot ft.gnuplot head.gnuplot - used to create many of the diagrams below
