Hey But thats the thing as I am directly connecting the transmitter and reciever as in grc... will there be any error(i dont think so) also can you tell me whether the packet length used is correct or not and is there a need for fec when the blocks are directly connected and no awhn or external is introduced. Can you look at my grc so that you will get an idea what i did.
