Hello again,
I have decided to try the GNURadio -> TCP -> MATLAB route. I am running
into a few problems.
First, I downloaded Jamie Cooley's GNURadio TCP Socket code here...
http://alumni.media.mit.edu/~jcooley/gr_experiments/experiments/gr_socket.ht
m
Then I downloaded a free matlab TCP toolbox as David suggested.
http://www.mathworks.nl/matlabcentral/fileexchange/loadFile.do?objectId=345&
objectType=file
I can set up the connection and send data to matlab, but the data I receive
is all messed up. I think the format is off. For those who have done this,
what data type are you sending and how are you receiving it? Currently, I
am just sending a complex sine wave. If I sink it to a file, I can open it
in matlab with no problem. But when I send it via TCP, I get garbage.
My matlab commands are basically...
Con = pnet(sock,'tcplisten');
data = pnet(con, 'read', 1000, 'SINGLE');
cdata = data(1:2:end)+j*data(2:2:end);
plot(log(abs(fft(cdata))))
Is 'SINGLE' the correct type to use? (I tried all the others and I still get
gargabe).
Thanks for the help,
Kevin
