In order to utilize the frquency resource adequately and increase the capacity of mobile communication system, the wireless electric wave propagation of existing mobile system always adopts the microcell structure. forecasting the path loss characteristic of electric wave accurately can provide the necessary condition for the layout and design of wireless network, at the same time it is a precondition for the research on the microcell mobile system. the methods of forecasting of wireless electric wave propagation can divide into two parts : one is pluse and respond, that is establish the empirical model based on experimental and statistical data ; the other is ray tracing method, that is establish the deterministic model based on theoretical analyse. the paper discuss the characteristic of wireless signal electric wave transmition in symmetrical atmosphere of earth, and introduce the common path loss transmition model in land mobile communication system, also point out the localization of these models based on experiential methods
而精確預測無線電波傳播路徑損耗特性，則為合理的微蜂窩無線網路規劃、設計提供了必要條件，同時也是研究微蜂窩移動通信系統性能的前提。無線電波傳播預測的方法分為兩類：一是用沖激響應法，即根據實驗、統計所得數據建立經驗性傳播預測模型；另一種是用射線跟蹤方法，即依據理論分析來建立確定性的傳播預測模型。本文首先討論了在地球表面均勻大氣中的無線電波傳播的基本特性，介紹了陸地移動通信系統中常用的幾種電波傳播路徑損耗經驗性預測模型，並指出了這些經驗性傳播模型對于微蜂窩小區無線電波傳播特性研究的局限性。 -

It is one of the important parts for the control of hupqc to detect the reference compensation signal. the predictive strategy is presented based on wavelet theory, that means tracing the fundamental signal and replacing with sampling data every half cycle. the fundamental signal is forecasted step - by - step in a half cycle earlier
補償指令信號的檢測是電能質量調節裝置的控制環節之一，本文提出了基於小波理論的預測檢測策略，跟蹤基波信號，以半周期為采樣更新速度，應用小波變換法對信號的基波分量進行遞推式預報，並取其與實時信號之差做為參考，然後產主與之大小相等、相位相反的信號作為hupqc的實時補償指令信號。
