摘　　要：调频信号具有优良的航天器飞行尾焰抗干扰能力,被广泛地应用于火箭和导弹遥测信号传输。传统硬件逻辑电路结构复杂、修改时间长,而软解调具有修改简单等特点,但是软解调运算时间长无法进行实时解调。随着集成电路的发展,原先仅用于加速图形计算的GPU逐步应用于数字信号处理。设计了利用GPU的软解调,可以完成实时解调的要求。PCM-FM signal provides good anti-interference performance for aerospace-craft jetting out the flame and is wildly used on signal transport of rocket and missile.Traditional logic circuit has complicated design and requires long-time modification.Soft demod- ulation has simple structure and needs long-time demodulation, which cannot be used for real-time demodulation.With development of logic circuit, GPU-based soft demodulation technology is used for real-time signal processing, which can meet real-time demodulation requirement
