Hello Jonathon I have tried using the down sampler from synchronous labs, but encountered a lot many errors while generating USRP image. I think I need to check and understand the differences and implement those. Also is there some other way I can achieve the divide the band without fractionally downsampling it. I need to divide the 25MHz gsm band into sub-bands of 200KHz for demodulation of GSM Signals
Thanks for the response.

Your best bet is to try to use the one made by Synchronous Labs a few years ago. Their code is on github here: https://github.com/SynchronousLabs/rfnoc-SynchronousLabs. Since it was built, RFNoC has had some changes that will need to be fixed, but I think this is your only option versus writing one from scratch.

I am trying to divide 25 MHz spectrum into 124 subchannels each of bandwidth 200KHz. I am capturing the signal at 200msps and I need to decimate it to 25.6msps(25MHz/128 channels). Please help me in understanding how this can be achieved using RFNoC, is there’s any block already defined for fractional downsampling.
