Hi out there,
I'm trying to send an ofdm signal. I don't want to tramsit any data, I only
want to see the reslting spectrum.
Now I'm wondering how to turn off certain carriers.
I know this is possible by adjusting the transmitted data but is there a
better way to do this?
For example by
Dear All,
I'm trying to correct for clock drift, and implement clock recovery,
reading data from a USRP1. I can't use MM clock recovery. The signal is
DSSS, and I can produce accurate estimates of the phase / timing error,
but not on a continuous stream in real time. I hope therefore to make
If someone writes a Fast Walsh Transform block, then 5.5 and 11 Mbit is
possible. Only a few changes need to be made to the MAC block to accommodate
this change.
Getting G (OFDM) to work seamless with B will be be a bit difficult I think.
You are then switching rates, 20 MHz vs 11 MHz if I
Josh,
Is there some separate program to convert old-style GRC
flographs (ie - grc_0.69) to the new-style ones required by
the GRC included with GnuRadio 3.2.2? I tried to simply
use GRC to open the older flowgraph (which worked fine on
grc 0.69 and gnuradio 3.1.3) directly, but got hundreds
You missed the window of opportunity. There was such code, it existed
for about a year in the svn trunk.
You need to checkout the svn trunk from about a year ago, and use that
grc/gnuradio to open the files (this will convert them). Now you can use
those converted files with the grc in the
It is possible I think. The current synchronization method only uses the
inserted preambles. If you don't change the preamble, it will not affect the
synchronization.
You may add a Code block into the transmitter diagram, also you need to
change some parameters of other blocks. But for the
