hi David
further to my previous email (pre requisite) :
perhaps something is mismatched for the application here. :
I have not been looking for long , but there are not many places where
there is amplitude calcs and a time constant.
------------------
ofdm.c
/* update mean amplitude estimate for LDPC decoder scaling */
ofdm->mean_amp = 0.9f * ofdm->mean_amp + 0.1f * sum_amp /
(ofdm->rowsperframe * ofdm->nc);
-------------------
best,
