It is recommended that you select TXT first or download the source file to the local machine. Sixth phase of experimental science and technology in December 2006 Experimental garden for College Students Three Design and implementation of multirate signal processing Chen Yiou, Li Guangjun University of Electronic Science and technology of China, Chengdu, 610054 Thirty-three Abstract: the multi rate signal processing is the basic theory of software radio, this paper introduces an efficient processing method of multi rate signal, which uses C IC filter and HB filter, F IR filter and polyphase filters for decimation and interpolation in order to achieve the purpose of changing the signal rate. This paper introduces the basic principle of various filters, analyzes the problems needing attention in the design and implementation, and gives the design results of digital down conversion with this multirate signal processing method. Keywords: multi rate signal processing; C IC filter; HB filter; decimation; interpolation; polyphase filtering in the graph classification number: TN92 document identification code: A article number: 1672-4550 (2006) 06 - 0113 - 04 D esign and Rea Liza tion of M ulti - Ra te S igna L Processi g n (University of Electronic Science and Technology of China Chengdu Abstract: M ulti 610054) - Rate signal p rocessing is a basic theory in softw a re rad io.
