I am trying to transfer a video by dvb-t using limesdr for past two months,but i am not able to do it successfully.  
I tried using all possible blocks but then the constellation which i get on receiver side is not same like which i get on the transmitter side.I do not know how to proceed further,meanwhile i have varied my code rates,transmission mode,modulation technique,frequency accordingly but receiver side constellation is too different(filled with noise) I have also tried using limesdr as a transceiver and then have transmitted using limesdr-usb and received using limesdr-mini but then the result was same.Can anybody help me out to fix my bug.
