Abstract :
The use of lattice structures in last years had been generalized in parametric signals analysis methods. There are a broad fan of coefficients calculation procedures not related between them, that seems to Show a different behaviour depending on the signal under analysis, and they are sensitive to the parameters selection. In the present work we try to eliminate the above problems by means an adequate parameters assignation depending on the local and global properties of the signal. This way one can obtain a broad field of applications algorithm that does not need set the parameters initially, allowing to the engineer an easy adaptation of its algorithm to the problem without the risk of a bad decision, with their sometimes bad consecuences in the algorithm evaluation, in setting some concrete values to the algorithm parameters.
