The FPGA Realization of Narrow-band Interference Suppression in GPS Receiver Using Frequencydomain Method

摘要：

The spread-spectrum gain of GPS receiver can provide certain anti-jam ability. But when meet with the strong narrow-band interference(NBI)environment,it needs to ask the signal processing technique for help to enhance the anti-jam ability. Compared with the time-domain processing technique , frequency-domain processing technique has the advantage of stabilization, quick constringency and effective repression to change interference. So it is applied extensively in engineering practice. This paper makes use of the advantage of FPGA to exploit every module of the narrow-band interference algorithm and carry out the algorithm in the Stratix-II chip, Altera. Debugging makes clear that the algorithm can meet the goal well.
