Detailed Documentation
This thesis project involves designing a program to investigate waveform coding efficiency and precision. The implementation focuses on designing Quadrature Mirror Filter (QMF) systems, including Conjugate Quadrature Filter (CQF) and Orthogonal Quadrature Filter (OQF) variants. The program employs batch processing algorithms to systematically evaluate waveform coding performance across varying filter orders, allowing comprehensive analysis of encoding characteristics. Key implementation aspects include filter coefficient calculation using Parks-McClellan algorithm, frequency response validation, and signal reconstruction error measurement through MATLAB's filter design toolbox and custom optimization routines.
