摘要: |
通过对通信系统信道部分产生组合干扰的原因分析,研究其消弱方法,并推导出宽带数字接收机抗组合干扰设计规律和方法。基于此规律,已设计并投入生产了一种宽带数字接收机,在硬件无任何改变的情况下,可完全适用于三种C频段系统。 |

Abstract: |
This paper discusses some reasons that can interfere with a wideband receiver. Some methods are introduced to reduce the interference. These methods have been applied to a real system and they can adapt to three different C-band systems without any change in hardware. |
