Thank you so much for your answer, Marcus. I understood everything. I'm going to try to build my own block. Have a nice day. On Tue, Mar 3, 2020 at 9:48 PM Müller, Marcus (CEL) wrote: > Hi Vinicius, > > you can directly feed the output of the OFDM channel estimation block > into a simple genera

Re: Wire shark output question

Dear Ranganathan, the two connections to the Wireshark block are for (1) the packets that are generated locally and (2) the packets that are received. It is the same kind of data, i.e., the bytes that are about to be send out/the bytes that were demodulated. If you disconnect "rxout" from the PHY

Re: DVB-T receiver problem (OFDM symbol acquisition)

Hello Ron, do you think it would be possible to use your block that detects the drift to adapt the sample rate of the source block automatically and if yes, how would I have to do that? When the position of the CP increases, the sample rate must be decreased and vice versa. Could it be done by a
