[Discuss-gnuradio] Best Resample Method For Resampling LTE Data

[Paul Creaser]

Hi,

I'm currently using the Rational Resampler in GUNURADIO to resample LTE
data, for example from 30.72MHz to 15.36MHz and 50MHz to 15.36MHz. I`m able
to decode the data, so every thing seems to be well.

I chose the Rational Resampler, simply because it is easy to use. However I
noticed, GNURADIO has a number of resample modules, Fractional Resampler,
Polyphase Arbitrary Resampler etc... I'm guessing each resampler has it`s
strengths and weaknesses. Perhaps one is better for audio, another is better
for LTE data etc..

At this stage, I have found the equations for the various resamplers, but
have no practical experience, with regards to the merits or demerits of the
different modules.

Any pointers to any online resources or offline books would be appreciated.
