Space - time codes can be divided into tree mainly parts : bell layered space - time architecture ( blast ), space - time trellis codes ( sttc ) and space - time block codes ( stbc ). in this paper, we mainly compare the performance of blast and stbc in many aspects, such as design criterion, transmission rate, diversity gain, diversity combining, bit error rate and channel capacity etc. in this paper, we first respectively analysed the instantaneous received symbol energy - to - noise ratio of v _ blast in the diversity combining methods of maximal ratio combining ( mrc ), equal gain combing ( egc ) and selective combing ( sc )
Mimo技術核心是空時編碼（ stc ） 。空時編碼主要分為三種:分層空時碼（ blast ） 、空時格碼（ sttc ）和空時塊碼（ stbc ） 。本文主要對分層空時碼和空時塊碼這兩種編碼方式在設計準則、傳輸速率、分集增益、接收合併、比特差錯率和通道容量等方面進行了較為詳盡的研究。 -
The essay mainly divides into four major parts. first, the definition of organization decision - making ; second, combing the development from the rationality choice to the limited rationality in the history of west social sciences ; third, analyzing importance of organization rules and regulations to organization decision - making and reasarching its limitati in onrationality ; fourth, exploring how the perceptual factor influences organization decision - making as well as what we can do to display its frontage function
基於理性選擇框架的組織決策理論在解釋組織現象時遇到了現實性的困難，西蒙在考察組織決策的實際過程時發現，人們在從事組織決策時的行為並非總是遵循理性選擇模式，而且也不可能達到一種最優選擇，所以說，基於理性選擇的決策模式只能是一種理想類型。 -
First, on the basic theory of the coaxial disk cylindrical waveguide, we analysis field equation in each area of the coaxial disk cylindrical waveguide with longitudinal ribs. the dispersion equation and the coupling impedance of this structure are obtained by means of triangle function ' s orthogonality and combing with the field matching method. through the numerical calculation, we discuss the influence of various structure ' s parameter on the dispersion and the coupling impedance
主要工作和創新成果如下：一、首先在盤荷波導理論的基礎上，嚴格分析加上脊后的各區場表達式，利用邊界條件和函數的正交性推導出對應的色散方程和耦合阻抗表達式，並通過數值模擬計算，詳細討論了該結構的幾何參數對色散方程和耦合阻抗的影響。 -
Based on the previous research and combing the situation of our country, this article elaborates prepayment. this article is divided into four chapters. the first chapter includes three sections
針對上述問題，作者在深入學習國內外研究成果的基礎上，結合我國國情，對提前償付行為及其治理做出全面而深刻的分析。 -
When mapping from design variable space to quality attribute space in the stage of concept evaluation of product design, the combing qualitative and quantitative method, rough set based mapping method and physical model experimentation based mapping method are studied. when making physical model experimentation, the transformation method of system condition is put forward for the first time
從設計變量空間到質量屬性空間的映射角度，提出了定性定量相結合的分析方法；研究了基於粗集理論的映射方法；研究了基於物理模型試驗的映射方法，並首次提出了進行物理模型試驗設計時的系統條件變化方法。
