    Abstract
  • For direct sequence spectrum system(DSSS) receiver in high dynamic situation, a fast PN code acquisition method was proposed. The acquisition method based on high-folded digital matched filter(DMF) and FFT is able to convert the traditional two-dimensional search method to one-dimensional search. The realization frame of 32-folder DMF in FPGA was put forward. The simulation focused on the folder multiple and system resource shows that the larger the folder multiple is, the lesser the system resource costs. When the input signal SNR is -20 dB, the acquisition speed of this method is much faster than the traditional methods. This method has good characteristics of fast acquisition and system resource expended lower. Practical engineering verification shows that it can be used in high dynamic situation.
