Rejecting harmonic interference in twacs using iir notch filter based on all - pass filter
陷波器抑制工頻通信中的諧波干擾So the products designed in this way can not meet electromagnetic compatibility requirement and become flaw products 。 to prevent the above occurrence, it is proposed in this paper that emc design should be carefully treated in early product design. the methods such as grounding masking, filtering transient noise reduction are used to guarantee the electromagnetic compatibility
但很多工程技術人員仍沒有加以足夠重視,這樣設計出來的產品將不能滿足電磁兼容性的要求,成為一件有缺陷的產品。為避免上述情況的發生,作者在產品設計初期著重加強電磁兼容性設計,採取接地、屏蔽、濾波、瞬態干擾抑制等措施,以求實現電磁兼容。Digital signal processing technologies were used to produce spatial and directional beam in smart antennas. then the main beam aims at the coming direction of reference user and the side lobe points to the coming direction of interference user
智能天線是利用數字信號處理技術,產生空間定向波束,使天線主波束對準期望用戶信號到達方向,旁瓣或零陷對準干擾信號到達方向,達到充分高效利用移動用戶信號並刪除或抑制干擾信號的目的。Digital signal processing technologies were used to produce spatial and directional beam in smart antennas. then the main beam aims at the coming direction of reference user and the side lobe points to the coming direction of interference user. smart antennas are classified to switching - beam and tracking - beam
智能天線利用數字信號處理技術,產生空間定向波束,使天線主波束對準期望用戶信號到達方向,旁瓣或零陷對準干擾信號到達方向,達到充分高效利用移動用戶信號並刪除或抑制干擾信號的目的。Time delay notch filter design to reduce residual vibration of flexible structure
