摘要

In this paper, we analyze the performance of the single d-well code acquisition in severe Doppler environment. Both the carrier frequency offset and code frequency offset due to Doppler effect are taken into account. The effect of the code Doppler gives rise to the code chip slipping during the correlation process. Moreover, the power reduction through the bandpass filter caused by carrier Doppler can degrade the acquisition performance significantly. However, this issue can be alleviated by properly choosing the bandwidth of the bandpass filter in the acquisition loop. Results are presented for the cases which show that the acquisition loop can tolerate Doppler frequency offset at the price of a slight performance degradation.
