Noncoherent sequential PN code acquisition using sliding correlation is proposed. Noncoherent detection and chip asynchronization is taken into consideration, while frequency offset and data modulation can be simultaneously taken care of. To realize the sequential detection, the I/D cross-correlation under out-of-lock has to be modeled as a Gaussian random sequence to avoid the significantly high false alarm probabilities caused by the conventional zero sequence model. Extensive computer simulation results indicated that the proposed PN code acquisition can achieve low false alarm and missing probabilities.
