%X The article provides applying DSTC(Deskewed Short-Time Correlator)to code acquisition system on serious code frequency offset. Firstly, performance of acquisition system affected by code frequency offset is analyzed. Considering complication and performance of algorithm, code frequency offset is compensated by using DSTC. Secondly, specific and realizable solution of code acquisition system is given. Finally, probability of detection of acquisition system before applying DSTC is compared with that after applying DSTC, And it is confirmed that applying DSTC can greatly improve probability of detection, which is important for code acquisition in low signal-to-noise rate.
