Is that your concise description of coherent detection?

Bet you do not know what 'coherent detection' is.

because if you did, you would not have written that.

Ok, now rent a brain for a day, and thinks.

*IF you have an AM receiver, and set the transmitetr carrier to zero,
as in the case of DSB-SC with no modulation (= silence remember),
then what WOULD you hear?
I will tell you: All the noise in the band.
Not good for silence, specially if good conditions exist!

So you could have figured that out if you had been created with a brain.

Also, you did not bother to look up the waveform, you just write some bull,
never even designed a DSB-SC transmitter, much less ever used one.

No this is perhaps not a politically correct answer, but hopefully you
wil lread those papers, gooogle DVB-SC, and learn something, and then
stop spreading dis-information.
