利用二阶循环平稳特性识别GSM和LTE信号
Identification of GSM and LTE Signals Using Their Second-order Cyclostationarity
摘要：
自动信号识别（ASI）在军事和商业上有着广泛的应用，如频谱监测和认知无线电。提出了一种基于导频诱导二阶循环平稳特性的ASI算法，用于GSM和LTE信号的识别。该算法在低信噪比和短观测时间下具有很好的性能，不需要进行信道估计和定时频率同步。使用ThinkRF WSA 4000接收器采集的模拟和非广播信号来证实这些发现。
英文摘要：
Automatic signal identification (ASI) has various millitary and commercial applications, such as spectrum surveillance and cognitive radio. In this paper, a novel ASI algorithm is proposed for the identification of GSM and LTE signals, which is based on the pilot-induced second-order cyclostationarity. The proposed algorithm provides a very good performance at low signal-to-noise ratios and short observation times, with no need for channel estimation, and timing and frequency synchronization. Simulations and off-the-air signals acquired with the ThinkRF WSA4000 receiver are used to confirm the findings.
