An Anti-Jamming GPS Receiver Based on Subspace Decomposition Method

Code delay and Doppler shifted frequency would not captured using the conventional GPS receiver in the strong interference case because the received GPS signals which traveled a long distance were very weak. In the paper design of an anti-jamming GPS receiver is proposed. First, the interferences in the received signals are canceled through subspace projecting technique and the resulting interference-free signals are processed by a weight vector which maximizes signal-to-noise ratio. Finally, the simulation result has shown that the method is valid.
