基于GPU加速的扩频信号捕获方法
Acquisition method with spread spectrum technique based on GPU acceleration
摘要
Abstract
The acquisition of spread spectrum signal is an important part of the DSSS( direct sequence spread spectrum) receiving system. For solving the existing problems such as heavy calculation and low speed, the acquisition method based on the GPU acceleration is proposed. The acquisition method based on the cyclic correlation is converted into the process of CUDA thread blocks, and then the process of acquisition is executed completely through GPU. The simulation results show that the method based on GPU improves the executive efficiency of DSSS systems.关键词
