The model for a QPSK bandlimited DS SS system is presented firstly. With maximum likelihood estimation (MLE) criterion, two kinds of parallel acquisition algorithms, which are based on data modulation and non data modulation, are introduced respectively. Specifically, when signature code is m sequence or Gold code, the computation of non data aided algorithm can be reduced by Fast Hadamard Transform (FHT). The application of FHT is discussed and simulations are carried out, which show that the acquisition performance of non data aided algorithm outperforms data aided algorithm.
