Abstract:

For GPS interference problems,the common method in the signal processing system is to achieve interference using the adaptive nulling algorithm.This paper presents a signal processing system hardware implementation scheme together with an algorithm.First,the architecture of the GPS nulling antenna is described,then the paper gives the signal processing hardware design ideas and implementation of functional modules.Finally the results of the measured data show that the hardware modules can meet the requirements of the adaptive nulling algorithm.

Key words: adaptive nulling antenna;hardware design;signal processing system;FPGA
