Fast Acquisition Method for DSSS in the Presence of Sampling Frequency Offset
Doyoung Ham, S.C. Kim, Jeong-Hoon Park, Seong-Cheol Kim · IEEE Communications Letters · 2023
We present a fast acquisition method for direct-sequence spread spectrum systems. By considering sampling frequency offset, the algorithm enables higher coherent integration time and high sensitivity. The proposed algorithm is almost as fast as conventional methods, which do not consider sampling frequency offset.
