Abstract :
A 2-D lattice filter with six reflection factors in a stage is proposed as a general lattice filter. The authors also propose the adaptive algorithm of 2-D lattice filter and give some considerations on convergent rate of lattice parameter estimation. Then an improvement method on the convergent speed is proposed. Some examples show that this method improves the convergent speed of parameter estimation
