2017-07-04 Thread MUHAMMAD AHMAD
Hi,

I am using ubunto 10.04  and uhd 0.003.003.001 .
but when i connect b200(NI 2901) i receive error ( No dvices found).

I think i have old uhd version and my Ubunto is not supporting latest uhd.

can i upgrade this old version using any command?

[Discuss-gnuradio] OFDM Receiver

2017-02-22 Thread MUHAMMAD AHMAD
Hi,

I am referring the built in  example of gnuradio companion  ( rx_ofdm.grc).
In which I replace random source with usrp source.
on Transmetter side I am sending some bits and in receiver flow graph
(rx_ofdm ) I am facing problem where I have to attach file sink to get
 these bits.

I attached *File sink block* after *bits repack* block but I did not
get any data in file.
I also have attached *File sink after stream CRC32 block but*  I did not
get data in file.

Kindly inform if possible where I have to attach file sink in flow graph to
get receiving bits.

Here is an Attached flow graph modified form of (rx_ofdm)

Thanks in anticipation.
