Hello everyone
as part of my final year project i would like to know if any of u have got a code for implementing forward prediction using LMS. I have myself tried to write a code on MATLAB but it i am simply not able to predict a large chunk of data( here i have taken the desired signal as a cosine wave). i feel i should perhaps try to train my weights with some more data ( here i had considered around 10,000 samples).
also i am able to predict the signal if my fmfs=10*fs where fm is the freq. of the cosine wave and fs is the sampling frequency. i fail to understand why the code doesnt work if i increase fs to a large value. Please help !

Added after 1 minutes:

fm= fs* 10 and not fmfs=fs*10 as was mentioned in the previous post
 

Hello there,

LPC is a speech encoding technique, that uses a Stochastic based aproach. It models your mouth probabilistically, like your vocal cords and models the the voice and subtracts it from the original one. the error you get is sent over the line and hence saving bits, and geerates it similarly at the recieving end.

Its not a good idea to ask for the code, I can provide you with it but I think you should try by your own, its not that difficult.

Regards
Qasmi
