Please , advise me if there is another method to understand the blocks. I wonder if I can enter my parameters directly in ofdm loopback example without understanding the code and then getting the system works fine during implementation using USRP.I think maybe there is something wrong in installation also , so I am reinstalling GNURADIO now.I want to make OFDM system with some requirements on parameters. I don't know how to start . I think I must start by synchronization part as it is the most important part . So to understand how the synchronization is done in GNURADIO , I have to understand the c++ code of the synchronization blocks. But since I found the c++ codes difficult to me to understand and there are too many variables ( I am not new to c++, I used it for 5 years but some concepts like polymorphism are new to me ) , I decided to cout all variables in the hope that it helps me understanding .

what you're expecting to gain from this exercise. You're going to see
a bunch of numbers fly by really fast. Wouldn't plotting the output
with one of the waveform analysis tools be more useful?
