Abstract

The invention provides a parallel filtering method, system and device for 5G ultra-bandwidth high-speed signals, and the method comprises the steps: inputting a group of parallel high-speed signals, and carrying out the at least one-stage multiphase decomposition of the parallel high-speed signals; if the factors of 2, 3 and 5 are contained in any multiphase decomposition branch, continuing decomposition until the multiphase decomposition branch is decomposed into a filter with a single working frequency, and filtering and outputting a multiphase decomposed filtering signal; and performing addition, subtraction and delay processing on each stage of output filtering signals, and outputting the processed filtering signals in parallel. According to the invention, an input high-speed signal can form a plurality of filtering signals with shorter data rates and shorter coefficient lengths in a multi-stage step-by-step decomposition manner, so as to realize parallel filtering output of a broadband high-speed signal. And meanwhile, by cascading a plurality of two-phase, three-phase and five-phase filter units, parallel decomposition of any filter meeting a corresponding multiple relationship can be realized, so that different parallel filtering requirements in actual 5G communication are met.

Description

technical field [0001] The present invention relates to the technical field of 5G communication, in particular to a parallel filtering method, system and device for 5G ultra-wideband high-speed signals. Background technique [0002] The fifth-generation mobile communication technology (5G for short) is the latest generation of cellular mobile communication technology, and it is also an extension of 4G (LTE-A, WiMax), 3G (UMTS, LTE) and 2G (GSM) systems. 5G mobile communication technology optimizes the frame structure on the basis of 4G, expands the subcarrier configuration parameters, supports 15khz, 30khz, 60khz, 120khz, 240khz, and supports 1008 cells at the same time. Through a series of technical improvements, 5g can support a maximum bandwidth of 400mhz, which has the advantages of large bandwidth, high speed, and high energy efficiency, and can meet the needs of various scenarios in the new generation of mobile communications. [0003] In the practical application of ...
