  1. The theoretic formulas imply that mimo system can make use of multipath fading in full of scatter enviorment and its channel capcacity is in proportion to the transmt or receive antenna. 2. paper mainly explains the basic principle of bell laboratory layered space - time ( blast ) architecture

    2 .論文重點闡述了實現mimo系統中空間復用技術的貝爾實驗室空時分層（ blast ）結構的基本原理， blast結構作為實現mimo系統巨大容量的一種有效的手段，其核心是基於排序的串列干擾消除（ osic : orderingsic ）檢測演算法。
  2. The major job is manufactured a transmitter, which has three upmixer channels. its function is to up convert the signals from c - band to ka - band. the input local oscillator is provided by a low frequency crystal oscillator which has a good performance of phase noise, through 512 times multiply to ka band. this sysetem is used in the laboratory as transmitter source of the fuze, for the multidimensional objects in practise, which lead to the complexity of the reflect signal, so the amplitude, frequency and the phase of the transmit signals both have a key role in dealing with the reflection signals. therefore, this system requires for both the coherence of the single channel ’ s amplitude, phase and multi channels

    本文的主要工作是應用戶要求製作一具有三發射通道的上變頻系統，可以將c波段的微波信號上變頻到ka波段的毫米波信號。系統的本振輸入基頻由一相位噪聲非常好的低頻率晶振提供，經過512次的倍頻放大至ka波段。本系統作為實驗室中引信的發射源，由於目標反射信號具有時變的多維性，反射信號變得極為復雜，在信號處理時，不僅信號幅值、頻率有決定意義而且相位關系也很有決定意義。
  3. In this work, according to the feature of soft x - ray fluorescence, a setup has been established for the measurement of soft x - ray fluorescence in laboratory, which is calibrated by 55fe. the setup is made of x - ray tube, fine tuning table, vacuum system, gas - flow proportional counter and multiple channel analysis

    本文工作中依據軟x射線熒光的特點，在實驗室建立了一套軟x射線熒光測量裝置，該裝置由x射線管、精密微調樣品臺、真空系統和流氣正比計數管探測系統以及多道分析儀組成，並採用~ （ 55 ） fe標準光源對系統進行實際標定。
  4. In order to deal with the problems in high institutions, such as insufficient investment in basic research, weak contingent in scientific research, few and decentralization of s & t resources, distempered mechanism for industrializing s & t achievements, and so on, it puts forward some suggestions, namely extending investment in basic research, organizing research institutes in terms of u. s laboratory mode, actively supporting the construction of technical transfer platform, smoothing the transformation channel for s & t achievements, and something else

    摘要針對高校基礎研究投入不足，研究力量簿弱和科技資源「小而散」 ，成果產業化機制不暢等問題，提出加大基礎研究投入，借鑒美國聯邦實驗室模式組建研究院和積極支持技術轉移平臺建設，理順成果轉化渠道等建議。
  5. It has many benefits due to its ultra - wideband nature which including the following : not sensitive to channel fading, low transmit power, extremely difficult to intercept, low complexity of transceiver structure, fine range resolution ( centimeter scale ) for location and so on this paper combines uwb technology and mobile ad hoc network technology, concerting the lasn project of national key laboratory of communication, researchs the baseband process cell of uwb communication transceivers on the base of arithmetic research and spot test

    本文結合uwb技術和移動自組織網（ manet ，即mobileadhocnetwork ）技術，配合通信抗干擾技術國防重點實驗室uwb技術研究項目「 lasnproject 」的工作進展，在演算法研究和現場測試的基礎上，對uwb通信節點樣機的基帶處理單元進行設計研究。樣機結構包含三大模塊:天線、用分立器件形成的射頻電路、由fpga構建的基帶處理單元。
