Abstract :
In order to solve the space spread spectrum TT & C system based on virtual radio is time-consuming, not a real-time system, the system put forward a method for fast acquisition of spread spectrum signals based on GPU. The system complete two parallel acquisition algorithm operate (time domain parallel and frequency domain parallel based on FFT) on GPU platform. To support the study on acquisition algorithm of control signal spread spectrum, simulation platform of spread spectrum signals fast acquisition based on GPU acceleration is built. Results show that the simulation platform with perfect function fast acquisition of spread spectrum measurement and control signal based on GPU, two kinds of parallel acquisition algorithm on platform of GPU than on CPU platform can be the fastest speed 50 times.
