seriously, we discussed this yesterday. It's a bit tiring to explain things in chat, and
then say exactly the same thing next day on the mailing list.
You cann't do it this way. Your framing must come from where you read the
Hi Ralf,
Good news!
Regarding your question, In order to be sure that what the block was
measuring was right, I've used a complete software transceiver together
with a Channel Model block. You may take a look at

Hi,
I assume the "Swap IQ" block is exactly what you're looking for.

Hi,
You could use a "Complex to Float" to separate the I and Q components,
followed by a "Float to Complex", inverting the re and im inputs.

Thank you for responding, but what I meant by invert is swapping the I
and Q components of the signal.
Dear Rachida,
in order to do that, use the "complex to float" and "float to complex"
blocks and connect the re output to the im input and the im output to
the re input.
Yours
Martin

Complex conjugate only inverts the imaginary (Q) part of the signal.
If you want to invert both, just multiply with -1.

Hi everyone,
I need to invert the I and Q of a complex signal. Does the block complex
conjugate do the job?
Thank you

Hello Federico,
after a lot of thinking I have finally managed to adapt your OFDM
Synchronization and TMCC Decoder blocks for DVB-T :-) The problem was
that the frame and symbol indexes in the tags sent by the TPS decoder
were not correct.
Although I can see the video now, I am not sure that I
