| 摘 要： | 根据联合战术信息分发系统（Joint Tactical Information Distribution System，JTIDS）信号的特点，提出一种基于多相滤波的JTIDS信号接收方法。该接收模型具有全概率接收JTIDS信号的特点，而且所需计算复杂度低。在信号接收后，通过能量检测对输出信号进行脉冲宽度检测，判断信号是否为JTIDS信号。仿真结果表明该方法在信噪比为正时具有较好的性能。

| Abstract: | According to the characteristics of Joint Tactical Information Distribution System（JTIDS）, a channelized receiver model based on ployphase filter is proposed, which intercepts JTIDS signals with high probability and requires low computation complexity. After reception, energy detection is used to estimate the pulse width which is utilized to decide whether a JTIDS signal is detected. Simulations show that the proposed method is quite effective when the Signal-to-Noise Ratio is positive. |
