Hi friends,
I wrote a gnuradio block that has 2 input streams.
1. The first stream is the stream of PN sequence data coming out of an
gr.xor_bb block. (It is a gold sequence generated by XOR two M-seq generated
using gr.glfsr_source_b).
2. The second stream is the data read from a

Where can I find schematics for revision 4.5 of the USRP? The latest
revision I can see in the Subversion repository is 4.2.
The schematics have not changed since rev 4.2. The only differences
were in the layout.

I agree with this because of the Beagle board and the efficacy of OMAP
processors for embedded SDR apps. With TI finally giving us free

How many usrps are involved in this?
How many usrp sinks and sources are you creating?
You should be creating 1 each for each USRP and keep them open the
entire time.

Thanks for all the discussions. It has definitely given me clarity into
what is happening. .
I understand that the DC component of the transmitted signal, along with the
frequency offset causes a strong tone at the receiver. I have linked two
