Hi all,
I'm trying to open the .DAT files that are generated by OFDM Module with
option --log but I can't. I have tried with cat, vim, vi, jeditor(with hex
plugins), open office. With excel and notepad open the archive but only with
ascii characters but I need to see the result of modulation.

Hello,
I want to get familiar with C++ applications, for example, here input some
integers and print the square of them( I have modified
howto_square_ff).
Now I want to input say -len=10 integers to "howto_square_vf" block and print
the
same number of squared results with "ACS_outputdata_vf"

RX samples per packet: 358
What your seeing is the print out for the number of samples per packet
(udp datagram). This is independent from the recv_buff_size, which is
the size of the socket buffer.

Hi all,
Since a few days, i'm trying to use UHD with USRP2/WBX under Windows Vista
Pro 64 bits. The rx_timed_samples example seems to work but it's impossible
to change the recv_buff_size and is really problematic since its default
size is very small (358 samples). Looking at the usrp_simple class

Hi,
Just a few general querys...
How long does it take for an RFX card to tune and lock to a frequency, once a
set_freq command is issued?
Does it matter if the steps are small or large, ie a greater swing on the VCO?
Is there a way to tell if/when the VCO is locked, ie its tuned (could I monit
Hi
On the output path of the FPGA there's a FIFO, Is 512 byte the size of each
packet stored in FIFO?
If true, why do I have option for fusb_block_size = 1024?
I think it would be better to send 512 byte packets instead of 1024 to avoid
fragmentation
Thank's in advance

Hey Lishan or Wh or whatever your name is...,
The part you posted from usrp_spectrum_sense.py is taken from
gr-wxgui/src/python/fftsink_nongl.py. There are some comments in the
code which tries to explain the gr.nlog10_ff-block: the variable
"power" is mentioned there.

Hello anonymous user,
Dear users,
Can anyone explain me what taps (in filter) means ? Any examples should be
great
Particularly in GRC which number should I give taps in filter bank, FFT
filter, filter delay, ?
Thanks a lot.
