摘要: An improved technique to design prototype filters for nearly-perfect reconstruction modulated filter banks and transmultiplexers is shown. This based on the frequency sampling approach, formulation presented as a multi-objective optimisation problem. Results indicate that new provides arbitrary-length with even better quality parameters.
