Thank you Mortiz for your reply. We are trying to basically do all the processing of the data in a program, without passing it through blocks, like a basic code. We are using Fortran for two reasons, as its faster than C++ in certain aspects, and secondly, integrating the code (simple code, doesn't make use of classes etc) with NumPy seems easier.I would like to know if I take the data from USRP, write it to a file. Get the data from the file, start processing it via Fortran integrated in NumPy, and again using USRP transmit again, will that be efficient enough?
Why exactly are we wanting to do all of this, instead of just using the blocks - I mention again, because we don't understand how the C++ blocks of GnuRadio work, function.
