Abstract: A resource pool managing system and a signal processing method are provided in embodiments of the present disclosure. On the basis of the resource pool, all filters on links share one set of operation resources and cached resources. The embodiment can be adapted to support different application scenarios with unequal carrier rates while mixing modes are supported and the application scenarios with unequal carrier filter orders. The embodiment also supports each stage of filters of the supporting mode-mixing system to share one set of multiply-adding and cached resources to unify the dispatching of resources in one resource pool and maximize the utilization of resources, and supports the parameterized configuration of the links forward-backward stages, link parameter, carrier rate, and so on.
