reflected pulse meaning in English

反射脉冲

The goal of the filter is to improve the sensitivity of an optical receiver by optimally filtering a communication signal . in this paper we calculated the temporal response of the matched filter , the commonly used f - p filter , as well as the matched weak ofbg filter . we find that the reflected pulse of weak ofbg closely resembles the triangular shape characteristic of a perfectly matched filter
论文计算了通信系统中矩形光脉冲信号经强、弱ofbg 、匹配光滤波器、 f - p滤波器的输出光脉冲波形，经分析比较后发现：弱ofbg和理想匹配光滤波器的输出信号波形极其相似，不存在码间干扰，而f - p滤波器的输出波形存在比较严重的码间干扰。
