| 摘 要： | GSM信号是一种广泛分布的通信信号。本文简要分析了GSM信号的结构特性,给出了基于实测数据的GSM模糊函数并进行了分析,然后通过对各天线阵元接收的信号与参考信号作时频二维互相关并依靠波束扫描,给出了测定直达波方向的一种比较精确的方法,同时,通过计算机仿真验证了该方法的有效性。

| Abstract: | The GSM signal is a widely distributed communication signal.The structure characteristic of GSM signal is simply analyzed;the ambiguity function of GSM signal based on the measured data is given and analyzed.A method of precisely determining the direct wave direction is given by cross correlating the signals received from various antenna elements with reference signal in time and frequency dimensions and depending on beam scanning.Meanwhile,the effectiveness of this method is verified with the computer simulation. |
