Hi Josh, I've check the documentation and also my variables. I've found that my list is a PMT pair or PMT dict: std::cout << std::endl << "checking if pair:"

Hi Josh, I've checked this information and it is very useful. I've solved several issues that I had before. However, it is still complaining when I post a BLOB_METADATA (which is a pmt_list) downstream. What I have is the following: BLOCK 1 --- > BLOCK 2 (both blocks use message passing as blobs

Hi Tom, thanks for you feedback. I didn't try your suggestion yet. But my professor help me to solve this in a different way: we put a divisor after the FFT (the divisor value is the same as the FFT size). Its related to the equations associated with the FFT and IFFT: in a real system the FFT (or
