摘要
同步是任何通信接收机实现的基础。针对同步系统的干扰是实现灵巧干扰的一种方法。在研究OFDM系统利用循环前缀实现符号定时同步算法的基础上，分析了干扰同步系统的可行性，并对不同干扰样式的干扰原理进行了理论分析，通过大量仿真进行了验证。研究表明，基于同步系统的灵巧干扰，能够以较小的代价取得较大的干扰效果。
Synchronization is a key process of any communication system. Jamming to the synchronization is a method of smart jamming. After the research of the OFDM timing synchronization based on the cyclic prefix, the feasibility of jamming the synchronous system is proved, and different jamming strategies have been analyzed. Computer simulations are provided. It can be concluded that jamming to the synchronization performs well with low cost.
