Chapter 2 introduces the principle theory of lna, harmonic mixer, multiplier, spdt, vco and the basic design flows of the ads examples ( x - band ), the power combine technology, the millimeter - wave power amplifier mmics ’ trends nowadays
第三章介紹了毫米波前端中無源電路的設計,包括毫米波窄帶濾波器的設計、微波和中頻濾波器的設計、波導到微帶的過渡、微波信號的層間過渡。The latter primarily improves the transmission distance and reliability by selecting the repeater automatically. the frequency domain auto - adaptatation filter algorithm is deduced and reliabity by selecting the repeater automatically. the frequency domain auto - adaptaion filter algorithm is deduced and a method of frequency domain algorithm to restrain the marrow band interference is given on the foundation of the time domain minimum mean square error auto - adaptation filter. then the meter reading system to can learn the power network structure and automatically create linked path by using neural networks auto - study ability and analyzing the reading data
後者主要是對中繼節點的自動選擇,以提高信息的傳輸距離與可靠性。針對電力線擴頻通信通道的特點,在時域最小均方誤差自適應濾波演算法的基礎上,推導了頻域自適應濾波演算法,並提出了頻域演算法抑制窄帶干擾的具體方法。運用神經網路的自學習方法,通過對抄讀數據進行分析,使抄表系統感知電網拓撲結構,自動建立中繼路徑。We designed a wireless asymmetric physical layer link model with a direct sequence spread spectrum system as a transmitted reference. uplink and downlink are both one - way links connected by an ip tunneling. uplink is consisted with the narrowband radio data link of the warfighter information networks ( win )
研究了無線非對稱鏈路,提出了一種用參考法直接序列擴頻( dsss )實現的無線非對稱數據傳輸的物理層鏈路模型:利用現有戰斗員信息網電臺的窄帶數據鏈作為上行通道,通過ip隧道技術保證單向鏈路的連通性。
