Predictors

Hello,	
  could somebody write me a list of predictors used for data compression 
in transmission and maybe some books where I can read about them? I 
could find only a little about Linear Predictor (forward and backward).

Thanks

There are many algorithms to compute linear prediction coefficients
(if that is what you mean). Here is a list of the better known
methods:

- autocorrelation method (aka Yule-Walker method)
- covariance method & modified covariance method
- Burg method (aka Maximum Entropy method)

There are many more, they usually differ in the domain (lag, time or
frequency) and the error that is minimized. There is an intorductory
section in Proakis&Manolakis "DSP" on linear prediction.

Thanks for that. But are there any other predictors? Or is there only 
the linear one?

I'm asking, because I do not know anything about it. I am studying Power 
    Electronics and Control. In two weeks I will have an exam and there 
will be a professor from Data Transmission Institute (I am not sure if 
it is correct english name). He told me that he will ask me about 
predictors in data transmission (for compression purposes mostly). The 
only one thing which I found and which was called predictor is the 
linear predictor. Of course just like you told it's weights can be 
calculated in many different ways. But I think he meant that there are 
other predictors, not only linear. Do you know any names of them?

Thanks.
