On the basis of the requirement about multi-rate processing technology in practice signal processing,this paper introduced a variable baseband multi-rate algorithm which is composed of formingfi lter, cascaded half-bandfi lter and fraction interpolationfi lter, used to implement variable baseband multi-rate processing. Gate through Simulink simulation and FPGA implementation, verifi ed this algorithm's performance and realizability.
