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.

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
