Hey Marcus,
as you say, for a lot of science you don't get high rates – so I'm really less worried
about that. More worried about Excel interpreting some singular data point as date; or, as
soon as we involve textual data, all the funs with encodings, quoting/delimiting/escaping…

Hi Adrian,
for CDMA, two things need to be different:
1. you need at least one orthogonal other sequence used by another user / data stream –
that MA in CDMA is multiple access :)
2. In classical CDMA, you would need your data to be a constant that you multiply with
your sequences – if you mu

Hi Marcus,
In QO100 there are Doppler shifts (that is the reason of the 200 Hz shift in
flowchart).I have already implement a flowchart of calculating it using the
middle BPSK beacon of QO100 using the frequency error of costal loop.My ground
station is equipped with GPSDO.I have already do sp
Hi,
I have already make a proposal that with fh=False a multi user CDMA can be
used.Each user will have a unique time in sawtooth shifting, the same time he
can see all other Tx signals.Each Tx will be seen as 'constant frequency' as
all users shift frequency the same rate.I do not claim that i

Those should be on the narrowband transceiver on a slightly different band!
Cheers,

You are confusing data representation with data presentation. The flaws in
Excel are NOT issues with the data format. So long as the data format clearly

Sorry again, never mind... I found the problem.
The source code for reading the data does not include the fact that I am
reading complex data and also three streams. Change the one line to:
