ac2rc (Signal Processing Toolbox)

Convert an autocorrelation sequence to reflection coefficients

Syntax

```
[k,r0] = ac2rc(r)
```

Description

[k,r0] = ac2rc(r) finds the reflection coefficients k corresponding to the autocorrelation sequence r. r0 contains the initial zero-lag autocorrelation. These reflection coefficients can be used to specify the lattice prediction filter that produces a sequence with approximately the same autocorrelation sequence as the given sequence r.

Remarks

You can apply this function to real or complex data.
