OT Not a lot of people know this

Found on another NG, and I'm pretty sure this guy knows what he's talking about, but so incomprehensible it's worth committing to memory for winning any known pub argument.

'DVB-T has been shown to outperform DAB with all other things being equal in a mobile environment because DVB-T uses synchronous modulation of the OFDM subcarriers whereas DAB uses differential modulation of the subcarriers and differential modulation carries a BER penalty because if one bit error occurs the next bit will also be in error with a very high probability because the demodulation is based on phase differences rather than absolute phases, so synchronous modulation recovers immediately.'

everybody knows that. slight mistake though- the thingymewahtsit does not outberhogemedoodle the whatsitsname- the two are anti -parallel and hewdonomous.not to mention antidaephobic (the fear that somewhere a duck is watching you, apparently)

Thanks for clearing that up!

I can sure sleep at night now

Cheers,

So, if I'm understanding correctly.

Digital radio will not work very well in cars because the error correction is rubbish?

So drop one bit and you'll have to wait for an accidental coincidence of phase for your reception to come back?

Good grief.

The worrying thing is that I understood most of that. Sigh.

I think I've lost the will to live

Ditto. Sigh.

Not sure that I agree with it though - Time to check out the Benoit reference yet again
