On the other hand, recent advances in communication and modulation methodologice, as well as in adaptive digital signal processing and error detection and correction, have opened the way for the development of effective medium access control and physical layer protocols that support power line communications ( plc ) networks operating at speeds comparable to those obtained from specially wired and more recent wireless local area network in mid - 2001, an industrial standards organization called the homeplug powerline alliance, originally founded by 13 companies including cisco, motorola, intel, panasonic, and texas instruments, announced the completion of the homeplugl. o specification for a l. 0mb / s class in - home power line networking technology based on orthogonal frequency - division multiplexing ( ofdm )
但是，近年來通信和調制技術的發展，特別是自適應數字信號處理和錯誤檢測及糾正技術，使電力線通信技術出現新的mac層和物理層協議，其性能可以和一些專用有線網路以及最近十年流行的無線局域網技術想媲美。在2001年，一個由13個公司（包括cisco ， motorola ， intel ， panasonic ， andtexasinstruments ）組成的組成的標準組織? ? homeplugpowerline聯盟，頒布了完整的homeplug1 . 0規范，改規范使基於正交頻分復用技術，主要針對10mb s室內電力線網路技術。 -
Change of temperature will affect the data acquisition precision of a / d conversion circuit. in this paper, the principle of adc and the effect of the factors of a / d conversion circuit are analyzed, and the relation model of a / d conversion circuit temperature and accelerometer output is established. after compensating the temperature error by using the temperature model, the data acquisition precision of the accelerometer has been improved observably. thirdly, in the temperature control turntable, we perform the static temperature experiment of orthogonal accelerometers
文中分析了a / d轉換器的工作原理，以及影響a / d轉換電路輸出精度的各種因素，並通過多項式擬合的方法找到了加速度計靜態輸出隨a / d轉換電路溫度變化的規律。利用該規律對a / d轉換電路的溫漂進行補償，補償后加速度計的輸出滿足了測量精度的要求。
