基于DSP Builder的帧同步检出模型

摘要

基于信号在进行远距离传输的时候,不可避免地存在信号干扰、延迟、非线性失真等,为了确保数字通信系统传输的有效性,必须采用同步.按照同步的作用可以将其分为载波同步、位同步、帧同步和网同步.主要通过对帧同步的检出进行研究,设计了一种基于DSP Builder的帧同步检出模型,具体以常用的帧同步码组——巴克码为例,详细介绍了该模型的设计实现方法,通过软硬件测试验证,该检出模型切实可行.%Signal in long distance transmission, inevitably there is interference, delay, nonlinear distortion, etc, in order to ensure the effectiveness of the digital communication transmission system, which must be synchronized. According to the role of synchronization can be divided into carrier synchronization, bit synchronization and frame synchronization and the network synchronization. The mainly studies on the detection of frame synchronization, a frame synchronization detection model based on Builder DSP is designed take Barker code as an example, introduced the method to realize the design of the model, and finally through the software and hardware testing, the detection model is feasible.
