摘要
为了解决传统信道化接收机结构复杂、运算量大的问题,介绍了一种新的多相滤波宽带数字信道化接收机的实现算法。该算法由多相滤波的定义经过公式变形推导出,并引入了重叠一半的数字信道化滤波器组,实现了全概率截获。根据实际工程需要针对大带宽的信号对该算法进行了仿真,取得了较好的仿真结果。该算法是一种高效运算,适合弹上应用。
In order to solve the problem with complicated structure and high operation amount about the traditional design of wideband digital channelized receiver, a new algorithm about wideband digital ehannelized receiver which is to be built using a polyphase filtering architecture is introduced. This algorithm is drawed by changing the formula according to the definition of polyphase filtering, the half overlap ployphase filtering channelized receivers are presented and full probability receiving ability is realized. Based on the actual project, the system is simulated with wideband signals, and better result is receiverd. This algorithm is efficient and suitable for onboard application.
