相关干扰 meaning in Chinese

coherent jamming
correlation jamming

The signal format of gps is analyzed , the principle models and mathematical models are established , the ber performance is analyzed in a channel interfered with wide - bandwidth awgn , narrow - bandwidth awgn , transmitted signal , single - tone signal respectively . based on the results above interference methods are discussed and simulated . then the performance of code acquisition and code trace of a digital gps receiver are discussed . the modem of linkl 1 and link4a are modeled and their ber performances are analyzed and simulated in channel s interfered with awgn , single - tone signal and multi - tone signal respectively
建立了jtids的收发终端的数学模型，分析它在噪声干扰、相关干扰、互相关干扰下的误码性能，提出较佳的干扰方法和干扰码型，并进行仿真模拟；分析了gps的信号格式，建立了gps的原理框图模型、信号数学模型，并对其在宽带噪声干扰、窄带噪声干扰、转发干扰、单频干扰等情形下的误码性能进行了分析比较，提出相对较佳的干扰方法，并做了计算机模拟，针对一数字式gps接收机中扩频码捕获与跟踪环的特性进行分析；建立了link11和link4a数据链调制解调数学模型，对它们在噪声干扰、单音干扰、多音干扰等下的误码性能进行分析，最后对干扰情况进行了仿真模拟。
