摘要：
A new non-coherent sequential code acquisition scheme is proposed based on the joint detection of correct cells (H-1 cells). The comparisons of the ASN with that of the conventional cell-by-cell sequential detection code acquisition system show that at almost the same cost a significant improvement can be achieved and a much more robust mean acquisition time performance against the change of the code phase offset variation or the signal-to-noise ratio per chip (SNR/chip) can be reached. The analytical results are verified by computer simulations.
