Abstract
In order to acquire DSSS signal based on the PC platform, a method accomplished by GPU has been presented. In this method, one-dimensional search is used to replace the traditional two-dimensional search for PN code phase and Doppler frequency. For this algorithm, we study the influencing factors which are focused on initial phase of the PN code, Doppler frequency, symbol modulation and noise. Due to large number of FFT calculation in the algorithms, parallel processing in the GPU significantly improves the efficiency of operations, as compared with the CPU.
