Research on particle filtering signal source localization based on firefly algorithm

Abstract

With the wide application of radio communication technology, signal source positioning technology has gradually developed into one of the key technologies in the field of radio monitoring technology. At the same time, the requirements for signal source localization accuracy are getting higher and higher. This paper introduces the basic principle of firefly algorithm, and introduces the firefly optimization algorithm to optimize the particle degradation problem of particle filtering algorithm, and further optimizes the firefly algorithm on this basis to propose the adaptive firefly algorithm to optimize the signal source localization by particle filtering, and introduces the principle and process of the proposed algorithm in detail. Finally, the proposed algorithm is analyzed and verified through simulation comparison experiments. It aims to promote the in-depth exploration of this field through this research in order to solve more realistic problems.
