Zusammenfassung: | In order to solve the problem of GPS signal acquisition, an acquisition algorithm based on an improved genetic algorithm (IGA) is proposed in this paper. The IGA employs the technologies including the dynamic search range of parameter, the adaptive probabilities of crossover and mutation, and the small section method for generation of an initial population to search Doppler shift and code phase. Simulations and experiment results show that the proposed method can acquire the signal parameters precisely and rapidly. Consequently, the acquisition performance is improved. |
