Abstract:
Detecting and mitigating the effects of interference in a positioning system. A received signal is divided into a plurality of receive signal time/frequency (RSTF) values. A plurality of threshold values are determined based on expected energy values for the received signal. In one implementation, if a predetermined number of the RSTF values are above the threshold, the received signal is determined to be corrupt.
