Khalil, Here are some concepts you need to understand the capabilities of GNU Radio: - Complex Numbers, Negative Frequency - Digital signal processing - Frequency/Phase/Timing Offsets - Sampling rates / sampling theorem 1) Study the https://wiki.gnuradio.org/index.php/SuggestedReading

Hi Ali, the block "chunks to symbols" is a simple look-up table and actually this would have been a better name for it. Given an array A of size NxD, you give it an index i \in{ 0,1,...,N-1} and it gives you back the elements of the array in the i-th position, ie, A[i,0:D-1]. Which part is

Hi Ivan, You should be able to build an FPGA image with 2 FFT blocks and 2 window blocks. I have done something similar on the E310 where I have 2 FFT blocks and then 2 custom blocks which pass/discard selected FFT bins (and is actually reasonably similar to the window block). A couple of
