Hi Marc,
Currently, I am trying to implement correlation receiver using FIR
filters. I am looking into polyphase filterbank channelizer to implement
correlation, but currently unable to do so because I currently do not
know how to assign taps for channelizer.I should have pointed you at Tom’s article on PFB channelizers and
synthesizers [1].
Thanks, nice article! I am going to test it soon.
people actually trying to implement stuff!
ADC in N210 is sampling at 100Msps, so you are saying that I can get
processing gain (better SNR) if I set the USRP sink sample rate higher
than
IMsps i.e usrp_sink.sample_rate(3.125e6) instead of
usrp_sink.sample_rate(1e6) . Right ?
Also I read [1] that if I oversample by 2 then I gain 3dB in SNR, if
oversample by 4 I gain 6dB in SNR and so on, is that TRUE ? If this is
true
I can get a lot of SNR improvement because ADCs are operating at
100Msps.
… encourage you to read a lot of books [1] and papers on this.
Thanks for the link, nice stuff.
If you find something interesting, don’t hesitate to add a new heading
like “FSK demodulator technology” and add the references there; I think
this list is something that could use broader usage
Sure! I 'll do that.
discontinuity is somewhat physically impossible[2]. So these modulations
get the spectrum of a phase-jumping system, smoothed by the spectral
shape of the pulse shaping.
Thanks for the detail. Also, I got FSK modulator working using the VCO
