An optimal noise reduction linear phase filter banks based on FPGA
Hui Zhang · Information technology newsletter · 2011
To design an oversampled linear phase perfect reconstruction filter banks with lattice structure is an efficient implementation.Once the analysis filter banks are ensured,the structure of synthesis filter banks is determined,but there is still lots of synthesis filter banks for the parameters are flexible,in which choose a synthesis filter banks for optimal noise reduction.This paper implements the design in FPGA with DSP Builder,and simulate the design on function with Modelsim.
