Implementation of Cross-Correlation Interference Mitigation Algorithm for GNSS Receiver
Jianjun Hao · 2009
Cross correlated interference of strong/weak signals and mitigation algorithm were presented,along with its implementation.The strong/weak signal channels were separated to track each corresponding signal,respectively.The cross correlation between strong and weak signals was computed.The resulting values were corrected by using relative Doppler frequency shift and fraction code phase difference.The cross correlation was wiped off from weak signal channel to eliminate the interference.The method achieves higher sensitivity and is easy to implement.
