TPS Decoding in DVB T/H

Started by Unknown March 29, 2007
Hallo, everyone

I have just decoded the TPS in DVB-T/H before and after the channel
equaqlizer.
The result by me shows, TPS Decoding before the channel eqalizer is
more robust as after the Channel Equalizer even by TU-6 or AWGN
channel.
Can somebody tell me the reason?
My Channel Equalizer works fine for the data tone.
thans a lot

sorry. TPS means Transmission Parameter Signaling. It is defined in the Standard ETSI300744. TU-6 is the channel mode for typical urban situation with 6 Taps. Can somebody tell me, shall I do the decoding of the TPS before the channel equalizer? there is a us patent : http://www.google.de/patents?vid=USPAT7123669&id=4B17AAAAEBAJ&dq=dvbt+tps&jtp=1#PPA1-IA1,M1 they do it after the channel equalizer and even with the channel state information to decode the TPS. Is that realy needed? thanks for any answer !
