Abstract
The invention discloses an optimized design method of an M channel over-sampling modulation graph filter group. The design problem of a graph filter group is summarized into the design of four original filters; through the modulation of the four original filters, the integral design of the graph filter group is realized; the design complexity of the original filters is sufficiently considered; theoriginal filter design is performed under the condition of considering the complete re-configuration conditions and the frequency spectrum characteristics of the graph filter group, so that the integral performance of the graph filter group is improved. The invention provides a simple and effective solution scheme for reducing the design complexity and re-configuration errors of the graph filtergroup and realizing the signal recovery and re-configuration.
