【Abstract】 Modern 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 precision 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 experimental results achieved up to 14. 5 times speedup,the development of modern GPU technology brings to the communications signal processing new ways.更多还原
