Abstract
Compared with conventional communication systems, spread spectrum communication system has the advantages of anti-interference, multiple access multiplexing, strong confidentiality and so on. Therefore, spread spectrum communication has been widely used in civil and military fields. Acquisition is one of the core technologies of spread spectrum communication system. How to capture spread spectrum signal in the case of low signal-to-noise ratio and large Doppler frequency offset becomes the most critical link for the establishment of spread spectrum system. This scheme adopts a two-dimensional acquisition method based on FFT, which can combine time-domain search and frequency-domain search, and provide a two-dimensional spread spectrum signal acquisition method with high-precision through matched filter.
