hi all:
I found there is a program (pick_bitrate.py) about bit-rate in
the /gnuradio-example/python/digital/ .And there is one quertion confuse
me about this program.
There is a formula about bit-rate in the program such as bitrate
= converter_rate / interp / samples_per_symbol. I know the
converter_rate is 128Msam/s,so if I set the interp and
samples_per_symbol, I can get the bit-rate.and is it the same as in the
GRC?
In the grc, I can set the samples_per_symnol in the flow graph and the
interp in the usrp_sink.so can I calculate the bitrate through the
formula in the pick_rate.py?
Besides,I found there is default bit-rate value in the
benchmark_tx.py.so is that mean I can set the bit-rate through two
ways,one is said above,the other is diretcly set the bit-rate in the
program’s (benchmark_tx.py -r) option? and in the second way, the interp
is calculated by the formula.Am I correct?
thank
you!
