Abstract

In this paper, the optimal parameters of sections and step is decided by the outcome of the astringency and stability of reflectance in gradient adaptive lattice filter. An adaptive gradient lattice joint processing model of 3 sections for noise cancellation was established and simulated using a variety of EDA tools in a FPGA chip. Behavior level, register transfer level and gate level simulation results show that the design method can transfer the mathematical model into circuit model efficiently, and the method is suitable for handling the complex signal processing system such as adaptive filter.
