非合作OFDM信号的前导码识别与对抗研究

Identifying Preamble of Non-cooperative OFDM Signals and Research on Electronic Countermeasure

OFDM技术日益成为主流的通信传输模式,每一帧信号中的前导码都包含了大量的关键信息,承担着重要的通信职能。提出一种对非合作OFDM信号的前导码参数进行识别的算法,并为以OFDM系统为目标的通信对抗提出了新的思路。最后通过Matlab仿真工具进行了验证。

The OFDM technology has become the mainstream telecommunication transport technique. The preamble in every frame of the signal contains a lot of pivotal information, which plays a important role in telecommunication. This paper introduces an algorithm of identifying the parameters, including the preamble, of non - cooperative OFDM signals, and puts forward a new advice about the electronic countermeasure aiming to OFDM system. The idea has been simulated in the end by Matlab.
