前端數據調制器完成對計算機輸出的控制信號加密處理，將指令碼載送到一指定頻率點。終端收費控制器解調出控制信號，送至單片機尋址控制部分。單片機尋址控制部分接收經fsk數據解調器送來的信號，送入cpu單元后，解出不授權信號，然後向關斷部分送入信號，關斷部分利用pin二極體的寬帶工作能力以及關斷特性，實現對非授權用戶或者非法用戶的信號關斷，使之不能正常收視，繳費用戶進行開通正常收視，達到控制用戶通道的管理。We study the qos strategy in wireless networks. after understanding the wireless local network based on ieee 802. 11, we point out the problem that occur when a large msdu ( mac service data unit ) is to be sent in the dcf mode in wireless lan. when a msdu is divided into several mpdus ( mac protocol date unit ), the later mpdu will service as a important role
在此基礎上，我們研究了無線局域網中的服務質量策略，在對基於ieee802 . 11的無線局域網進行了充分了解的基礎上，提出了在無線局域網dcf方式下發送較大msdu [ 2 ] （ mac層服務數據單元）時會遇到的問題，指出當把msdu分片[ 2 ]成為一組mpdu （ mac層協議數據單元）進行發送時，隨著mpdus的不斷發送，排序靠後的mpdu將對整個msdu的發送時間產生決定性影響。This paper used bid bid - ask spread, rare of stock turn, martin index as liquidity index, adopted event method analyze the sample of a marketable companies on shenzhen stock exchange, analyzed stock response on bulletin day, 15 days before bulletin day, 15 days after bulletin day, and dividend day, 15 days before dividend day, 15 days after dividend day by test the liquidity indexes, also considered some factor ' s influence, such as about the scale of companies, quantity of stock, the trend of share index at bulletin day and dividend day
