Moving average Prediction Filter - G.729 - pchakre - Jan 24 12:33:00 2002

Hello, In the Section 3.2.4 - Quantization of the LSP coefficients (Pg. 12) in ITU-T Recommendation G.729 documentation, we have to use two switched 4th order MA prediction filters to predict tha LSF coefficients. Can anyone please help me out as to which type of MA predictors have been used here? Are they the forward type, average type or the reverse type. If anyone has any idea over this, please reply ASAP.... Thanx in advance... Pratul Chakre |
