Re: [10GBT] THP Fixed Set TF


Have you tried using the receive filter presented in "ungerboeck_1_1104"
with your precoder? If so what kind of performance do you get?

Dear All,

Further to our Nov meeting discussions on fixed THP TF set,
pls find for evaluation attached material outlining 3 TF sets.
This is aimed in combination with THP bypass option -- i.e.
four THP modes in total.

All simulations were performed in time domain as per
"vareljian_1_1104" and showed reasonably good performance
with relatively short (24-Tap and shorter) FFE. Performance
impact due to 7-bit coefficient quantization effects was
found to be very small.

Similar results were observed in simulations for a 2nd order
Tx LPF @ 200 MHz as per "ungerboeck_1_1104" in place of the
3rd order Tx LPF @ 400 MHz.

Hope, the posting will stimulate discussion on our, otherwise
relatively quiet, reflector.

Happy Holidays to everyone.
