I've used both the Fractional Resampler and the Rational Resampler so far with reasonable results. At this stage in the case of the Rational Resampler, I simply use the Interpolation setting and decimation setting to form a ratio (taps:None, Fractional BW:0), which then generates the required output sample rate.
One interesting point. When for example resampling from 30.72MHz to 30.72002MHz, I had a look at the FFTs using the QT Gui Frequency Sink. One thing that struck me was, the rational resampler was acting as a low pass filter. At both ends of the spectrum I could see a roll off. I am also looking at trying the Polyphase resampler. Well actually I have tried it, just I haven't figured out, how to choose the parameters yet! -- View this message in context: http://gnuradio.4.n7.nabble.com/Best-Resample-Method-For-Resampling-LTE-Data-tp51496p51509.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
