Abstract This paper presents a structure based on noncoherent-SPRT algorithm for the sequence acquisition under large frequency offset and low signal to noise ratio in DS/SS systems. The emphasis is put on the effect of frequency offset and partial correlation of GOLD sequence on parameters. It is shown by the theoretical analysis and computer simulation that the good acquisition performance can been achieved. And this structure can been implemented with moderate complexity.
