Fine C/A code acquisition algorithm for weak GPS signal based on averaging correlation and differential coherent accumulation
Published 2015-05-01“…Aiming at the problem of global positioning system (GPS) C/A code acquisition under weak signal conditions,a code acquisition algorithm based on averaging correlation and differential coherent accumulation was proposed.First,the strength ratio of the largest peak to the second largest peak was adopted as the decision variable; optimum decision thresholds can be obtained through the simulation probability of false alarm of all kinds of acquisition algorithms.Second,by setting the decision threshold,the probabilities of detection of different Doppler frequency deviation and signal to noise ratio (SNR) were obtained.Finally,acquisition sensitivities of the code acquisition algorithm based on the differen-tial coherent accumulation were compared with those of the code acquisition algorithm based on coherent and noncoher-ent accumulation and the code acquisition algorithm based on noncoherent accumulation.Simulation results show that acquisition sensitivities of the code acquisition algorithm based on the differential coherent accumulation are improved by about 2.0 dB than those of the other two acquisition algorithms under the same receiving data length condition.…”
