Hello list, I would like to transmit some data using gnu-radio. My data
is a binary representation of an ASCII string.
I wrote my own block that builds the frame (header, payload, CRC,
trailer) as an array of 256 bytes (0s or 1s):
gr_make_io_signature(0, 0, 0)
gr_make_io_signature(1, 1, sizeo
f u have connected Transmitter-FG
with USRP, then u can determine the "effective bitrate" of transmitter
by calculating it backwards from USRP-sink sampling-rate.
symbol-rate = usrp-sampling-rate / samples-per-symbol
bit-rate = symbol-rate * modulated_bits_per_symbol

Hello list,
I have a graph consisting of a modulator mixed with a signal source, and
a USRP sink.
I have it configured with a *sampling rate* of 720KHz.
When I run it, UHD fires the following warning (and transmission seems
fine).
The requested interpolation is odd; the user should exp

expert, just intermediate :)
Looking on-line,I found out that the function block diagram is something
like: CIC (Intepolation) -> half-band filter -> DAC -> TX. Can you
confirm it?
I appreciate.
