Hello,
I am using blks2impl dqpsk modulator/demodulator.
Since demodulator's "samples_per_symbol" value must be an integer >=2 and
USRP samples at 64 Msamples/s with a 2^(n) possible decimation, I have to
sample a 2100 kbps carrier (=1050 ksym/s).
I found two blocks that may apparently be used for resampling:
- rational_resampler()
- rational_resampler_base_xxx()
I am not sure of which one I should use. Does somebody know the difference
between them?
I've read that rational_resampler_xxx() is a high-level wrapper for
gr.rational_resampler_base_xxx but I don't understand what it means.
