GNSS Receiver Correlator Groups for Continuous Wave Interference Detection

The patent segments the correlation processing into multiple groups of correlators (first group, second group, third group) with different lag values. Each group processes the received signal independently and provides specific detection capabilities. This segmentation allows the system to detect continuous wave interference using a single antenna by distributing the detection function across multiple correlator groups rather than requiring multiple antennas.

The patent introduces a new dimension of analysis by processing the signal through multiple correlator groups with different lag values (first lag value, second lag value, third lag value). This creates additional processing dimensions that enable interference detection without requiring additional physical antennas, thus improving reliability while maintaining device complexity.

The patent performs preliminary actions by pre-defining the lag values for the different correlator groups (first lag value, second lag value, third lag value) and pre-establishing the correlation processing structure. This allows the system to quickly process interference detection without time-consuming computations during the actual detection phase, improving accuracy while minimizing processing time.

The patent maintains continuous useful action by continuously calculating the correlation products for all three correlator groups in parallel during the tracking phase. The system continuously monitors the correlation results and compares them against threshold values, enabling real-time interference detection without interruption to the GNSS signal processing workflow.
