One important component of radio resource management is power control, which has been studied extensively in the context of voice communications
功率控制則是無線資源管理中非常重要的組成部分,這在早期以話音業務為主的窄帶cdma系統中,已經做了很多研究。It was demonstrated that this sort of load - control apparatus has superior performance. we used a electric transmitter as the transducer to collect the sound signal, using the daq toolbox of the matlab to achieve the collection of the sound signal, and using the dsp toolbox of the matlab and the sound - launch technology to analyze the time - domain characteristic and the frequency - domain characteristic of the signal, chiefly analyze its short - time average amplitude, its short - time over - zero ratio and its estimate of the power chart and the average - period chart
實驗中使用了駐極體話筒作為球磨機聲音拾取傳感器,利用matlab中的數據採集( daq )工具箱實現對磨音的採集,利用matlab信號分析( dsp )工具箱和聲發射技術對磨音進行時域和頻域分析,主要分析磨音的短時平均幅度和能量、短時平均過零率、功率譜估計和平均周期圖。It makes many users share a lot of channels, and reduce the cost of the channels. the utilization factor of them is improved. it is flexible and convenient for users to extent, the price is low and its period is short, too
該系統利用多通道共用技術實現了擴音呼叫和電話對講功能,具有布線簡單、接線方便、擴展靈活、成本低、繩路利用率高等許多優點。The technique of the multi - channels sharing and the bus topological structure are adopted in the system, which does n ' t set the central switch and which not only can realize many users share a few explosion - proof channels, but also reduce the cost of the channels, while improving the utilization factor of them. the users " extension is flexible and convenient. the system has the functions of amplifying call and telephone talk
該系統不設主機,採用多通道共用技術和總線式拓撲結構,實現多用戶共用少數防爆繩路,降低了繩路成本且提高了利用率;用戶擴展靈活、方便:具有擴音呼叫和電話對講功能;工程布線簡單,費用低,工期短。The whole paper had been divided into four parts : the first part introduces the general situation of digital trunking system and its channel encoding, the recent development of viterbi decoding ; the second part studies the error control scheme, and the convolution decoding depth which is most fit to digital trunking system ; the third part introduces several low power viterbi decoder and its principle ; the last part proposes a united - decision estimating viterbi decoding algorithm
本文共分為四部分,第一部分介紹了數字集群及其通道編碼的總體情況, viterbi譯碼的發展現狀。第二部分給出了數字集群系統中話音通道差錯控制總體方案,並研究了適合數字集群系統的卷積碼的解碼深度。第三部分簡單介紹了各種低功率viterbi譯碼器及原理。Voice communications and data transmission made along beijing s expressway removed doubts in people s mind about speed of terminal movement and coverage radius of base station of tdd mode. as a result of the experimentation, the datang group and the siemens company plan to organize a large - scale td scdma field demonstration in the near future. according to technical personnel who participated in the field experimentation, with progress of the experimentation, speed of terminal movement allowed by the system can be raised further
經過在北京高速公路上所做的現場通話和數據傳輸試驗表明: td - scdma終端的移動時速可以達到125km ,基站信號功率覆蓋半徑超過16km ,且通話話音清晰,圖象傳輸穩定,這一試驗結果完全證明td - scdma技術標準完全符合國際電聯( itu )對第三代移動通信的要求,消除了人們對于tdd模式在終端移動速度和基站覆蓋半徑的疑慮。If successful, this work could lead to implantable silicon retinas for the blind and sound processors for the deaf that last for 30 years on a single nine - volt battery or to low - cost, highly effective visual, audio or olfactory recognition chips for robots and other smart machines [ see box on opposite page ]
要是成功的話,將可發展出只靠一顆九伏特電池,就可以持續運作30年的盲人植入式矽視網膜與聾人聲音處理器,或是可以應用在機器人與其他智慧型機器上的視、聽或嗅覺辨識晶片,不但價位低廉而且高效率(見29頁神經形態電子晶片研究團隊) 。Audio transformer : large transmission power, wide frequency range, stable performance. used for telephone, fax machine, vcd, dvd, and audio etc
詳細信息:高傳輸功率,工作頻率寬,性能問題。適用於電話機、傳真機、 vcd 、 dvd音響設備中。分享友人
