Implementation of Lattice Filter in MATLAB - Second Order Version

I would like to share my implementation of a lattice filter in MATLAB. This post focuses specifically on the second-order lattice filter implementation, which utilizes reflection coefficients and a recursive structure for efficient signal processing. The implementation demonstrates how to calculate forward and backward prediction errors using the lattice structure's stage-by-stage processing approach. I would greatly appreciate expert review and feedback on this implementation. Currently, I haven't mastered the methodology for implementing higher-order lattice filters, which would require additional stages and more complex reflection coefficient management. I warmly welcome discussions and collaborations on extending this to higher orders! For those interested, the key components include: - Reflection coefficient initialization and adaptation - Recursive computation of prediction errors - Stability considerations for filter coefficients Please feel free to share your thoughts or suggestions via zhoujoejx@163.net.
