摘要：Several methods of acquisition have been developed so far which aim at accelerating the acquisition process and detection of weak GPS signals. In many of these the search is parallelized in code or frequency space. However, sometimes the number of samples in code peri- ods based on sampling frequency is not equal to required number of Radix-2 FFT algorithm. So it is again comput- ing the DFT normal method without FFT. The main pur- pose and objective of this project is to implement a fast and robust for weak signal acquisition algorithm "Double Block Zero Padding Acquisition" (DBZP) for GPS L1 civilian signal. Technique is developed even for the signals where number of samples in the code period taken for corre- lation is not satisfying the required number for Radix-2 algorithm. It is also suitable for weak GPS signals acquisi- tion, which require Pre-detection, or integration (correla- tion) Time (PIT) to be long.
