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。Their input capabilities are limited to a few buttons or numbers, or entering data takes extra time, as happens with a personal digital assistant ' s ( pda ) handwriting - recognition capabilities. they have less processing power and memory to work with, and their wireless network connections have less bandwidth and are slower than those of computers hard - wired to fast lans
它們的輸入功能局限於幾個按鍵或數字鍵,或者像個人數字助理( pda )手寫體識別功能那樣,輸入數據要花很長時間,它們所擁有的工作處理能力和內存都較校比起那些通過計算機硬連線與快速局域網相連的連接,它們的無線網路連接帶寬較窄,速度也較慢。
