[srslte-users] Resampling functions in resample_arb.c

[Saverio Mercurio]

I found the resample_arb.c file which contains an implementation of a 
resampler using a polyphase filter bank. This resamples isn't actually 
used in the core srsLTE code. It's used in a couple of test modules 
(resample_arb_bench.c and resample_arb_test.c). Is this implementation 
specific to those tests, or can it be used for resampling of the data 
read from the radio? I know that you can change the sample rate of the 
hardware, but we're testing something in which the sample rate of the 
radio is kept constant.
