How I can create a correlate RFNOC block, I need a where that buffer radio samples... For more information (time-domain) correlate formula please refer to the below link:

I have a reference signal that should be correlated with the input signal received from the radio core(In USRP)...
It is possible to buffer radio samples in RAM for some operations???
any idea that I developed an optimized RFNOC correlate block?
I don't use FFT for correlating, I want to do it in the time-domain method...
thanks in advance

I would look at how existing RFNoC blocks like the FFT block or FIR filter blocks buffer samples and then "do things with them".   That is perhaps a vague answer,   but I'm not an RFNoC developer myself.  But other existing RFNoC blocks have the same "buffer' samples" requirement.
