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 . 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.
