摘　　要：现代信号处理和通信系统对信号的处理,正变得越来越复杂并且计算也越来越密集,如何提高这些领域中信号处理的运算速度和运算精度已经成为当今一个重要的研究方向,GPU由于其特殊的结构,使其非常适合用于加速数据运算仿真和图形图像分析。本文提出一种基于GPU的信号相关性并行计算的方法,通过实验验证得出基于GPU的数字信号相关性的并行处理方法明显优于基于CPU下的处理方法,实验结果最高加速比达到了14.5倍,现代GPU技术的发展给通信信号处理领域带来新的途径。Modem signal processing and signal processing for communication systems are becoming increasingly complex and computationally more intensive. How to improve these areas of signal processing and computing pre- cision computing speed has become an important research direction. GPU＇ s special structure makes it function well suited for accelerating data manipulation and graphical simulation image analysis. This paper presents a GPU-based parallel computing signal correlation method, it is verified by experiments that GPU-based parallel digital signal processing method correlation was significantly better than the CPU-based approach, the experimen- tal results achieved up to 14.5 times speedup , the development of modem GPU technology brings to the commu- nications signal processing new ways.
