Hi all,
I need to measure the time of flight with the accuracy in nanosecond, now I
found an ic that can measure the time in ns. So now I want to support fpga
to read the timestamp when receive and send a data package with modifying
the fpga firmware. Can someone estimate whether the usrp or usrp2
thanks mattso 2 usrps and 4 rfx dbs is enough for me ,and in usrp
multi-signals can be simultaneous.while when i send a 50K frequency signal ,and
receive it from two antennas ,through oscope i find the two IQ signals are not
synchronous，signal from the second antenna seems 1/4 wavelength ahead

This should be fixed in the latest git master.

Can you send to me (offlist) two files:
config.log
gnuradio-core/src/lib/Makefile
Thanks,

Hi,
I am trying to compile gnuradio from the latest development code but in both
of my computers I get the same exact error**.
I use gentoo and I will appreciate any help
Thank you

file_sink_c prodces complex floating point. Every 8 bytes is a complex
float, where the first 4 bytes is a float representing I, and the second
4 bytes a float representing Q.
if you were using numpy, it could be read with: numpy.fromfile(file,
numpy.complex64)

Dear all,
I'm wodering the format of data in datafile which produced by file_sink_c. I
used octave function read_complex_binary to read the data. Since the usbdata is
a 16-bit binary data sent from FPGA to usb controller, is the first 16 lines of
the data represent the first sample point of the

Hello everyone,
Incorporating a MATLAB *.so library, I have created a block using the

I never yet try to send a file with benchmark_tx.py but i think it is not very
hard. the .dat file is not the file that you want I think. it is the file whch

Hi,
I'm currently working on a project using the ucla ZigBee Phy
implementation for the gnuradio framework.
I need some help how to use boost python and smart pointers to manage
a shared memory block from both sides, the python and the c++ side.
It would be great if I could manipulate as lit
