Hi,
I am testing a transceiver link in ISM band using two USRP2+RFX2400, one
configured as TX and the other one as RX. I would like to test my own
FPGA program, so for now I have your FPGA codes in which I only changed
the signal driving the DAC in TX to be an square wave (+8191 or -8192)

Hi all, I want to use 8 bits sample. I use inband_2rxhb_2tx.rbf firmware. I
use set_format( ) set data format as width 8 bits and shift 8 bits
and the return true. But when I read data the data still 16 bits format. I
do not use gr stuff to read data, however I directly read data.
If I use 16 bits

Hi All,
I started working with GNURadio a few months ago as a platform for use
with a Visual Light Communication front end. I've had some good
success with the basic benchmark testing and implementation of a few
basic tests with GRC, but I'm curious as to what datarates have been

In GRC, I defined a message queue like below:
self.msg_q = gr.msg_queue()
It waits for the USRP transmitter, and read the message received in the USRP
receiver in the local machine, using the code like below:
m = tb.msg_q.delete_head()
But if there is no message sent. It seems t
Hello everyone, I must find a way to compile the FPGA project for the USRP2 to
continue my Masters. I use ISE 12.1
and the top project u2_rev3 in the repository
git://ettus.sourcerepo.com/ettus/fpga.git using all the files in different
makefile.
The compilation works well and I get the bin file

Hello,
I get a question about the half band
filter in the DDC. I found that the LO (local oscillator) in my

frequency, which means that the IF of the output signal is

Hi all,
Recently I want to implement a OFDM based multi-rate system, and I am using
benchmark_ofdm_tx/benchmark_ofdm_rx programs in ofdm directory. I know I can
use unlock/lock mechnism to disconenct/connect the exising blocks to change
modulation block, and it indeed works. However, I also notice

Just to notify, my ethernet works fine -- I could use wired internet to
connect to the Internet.
