Abstrakt:

Signal acquisition is one of the key signal processing tasks performed by global navigation satellite system (GNSS) receivers. It involves detecting the presence or absence of a signal by comparing it with a predefined threshold, which can be either fixed or adaptive. This study focuses on optimizing the threshold of the trimmed mean constant false alarm rate (TM-CFAR) detector under Rayleigh fading conditions, employing metaheuristic optimization techniques, due to their proven efficacy in solving complex optimization problems. Furthermore, two TM-CFAR detectors are applied to the data and pilot channels of the GNSS system. Their outputs are then combined using two logical fusion strategies: AND and OR rules. Simulation results demonstrate that the optimized thresholds improve the performance of the GNSS signal acquisition system.
