Hi
I have been working with Gnuradio and USRP N200 for about a month now and
about all this time I have never succeeded in transmitting digital voice
via USRP. My Proposed approach is like
audio source--->CVSD encoder>OFDM mod-->rational resample to
200k--->multiply with signal source

There is a major problem with the way tags are propagated in blocks with
non-integer relative rate. If the ratio is not a power of two, the numerical
accuracy of the floating point will cause the output tags to diverge from the
input tags. Consider the fractional resampler. It accumulates the t

Thank you to Nick Foster for pointing that out.

Hi,
The 802.15.4 spec says that the channels should be 2 MHz wide with 5 MHz
inter channel spacing.
Why does gr-ieee 802.15.4 uses a sampling rate of 4MHz instead of 2 MHz ?
Off course it works with commercial devices, but I am curious why 4 MHz and
not 2 MHz.

Sumit

Just wanted to note that space at the Cyberspectrum event on Wednesday is
limited, so you have to RSVP on the Meetup page by Wednesday morning.
Thanks a lot!

Dear all,
We're hosting a special meetup next week in the South Bay! It's the same
week as the DARPA Bay Area SDR Hackfest:

Dear All!
I am new to GNU-Radio. I have previously used MATLAB for packet transmission
and detection. Here is the problem, I am facing:
I have inserted zeros between the packets and transmitting the same packet over
and over again. In the packet formation, I have appended two preambles
side-by
