Design and Implementation of High-speed Systolic Array Model of Look-ahead Annihilation QRD-RLS Algorithm in Complex Domain
Modern military platforms integrate a large number of RF transceiver antenna systems in a limited space,resulting in serious problems of co-site electromagnetic self-compatibility,and interference cancellation technology is an important means to solve the problem of co-site co-frequency interference.High jumping speed and drastic changes in the environment increase the pro-cessing speed of the cancellation system.In this paper,a digital domain fast cancellation algorithm based on complex domain QRD-RLS algorithm is proposed,and its high-speed systolic array implementation structure is derived,and the implementation method is studied on Xilinx FPGAs.The simulation and measured results show that the real-time processing clock frequency of the high-speed systolic realization structure can reach 60 MHz,which can effectively realize the interference cancellation function and has a good engineering implementation.
