How to decode the pitch predictor contribute in G.723.1?

Started by Yidan Zhou October 11, 2002
I am reading the ITU standard document of the speech coder G.723.1.
In Section 2.18 Decoding of the pitch information, it mentions that
to calculate the pitch contribution, we need e(n). But it does not
mention where the variable e(n) comes from. If anyone knows the clue
to get the variable e(n), please do me a favor.
Thanks in advance!
