文摘:在研究瑞利衰落條件下正交空時分組編碼通道容量的基礎上，將其與多發送多接收天線系統的通道容量進行了比較.比較結果表明，正交空時分組碼雖編碼簡單，易於實現，但在通道容量方面存在較大的損失，損失的程度與編碼碼率、通道矩陣的秩及收發天線數等因素有關.進一步研究表明只有當編碼碼率和通道矩陣的秩都為1時，才沒有通道容量的損失Figure 1 : factors driving the amount of process discipline

其主要原因為:第一、一些影響駕駛風險或出險次數的因素是不可度量的。例如駕駛員的駕駛熟練程度，駕駛時注意力的集中程度，在緊張情況下做出反應的速度以及判斷的準確性等;第二、由於分類變量有限，可度量的因素也不可能全部包含在這些變量中;第三、由於道德風險的存在，對投保人的分組很難肯定是正確的。如有的國家的機動車保險中要求投保人告知他們的年行駛里程數，在這種情況下，保險公司很難採取什麼措施避免投保人的故意低估。The achievements are as follows : 1 ) the system model based on the whole course in of erp project theory have been put forward, erp ' s project are divided into three stages in this model, evaluation is divided into four parts, and the indexes that should been evaluated at each stages and relationship among these stages has been described systematically ; 2 ) at proposed stage, according to the characteristic of erp project, feasibility analysis should been carried out from seven respects such as managing foundation technological foundation, the fund foundation, personnel foundations, basic data, understanding and demand to erp and goal of the enterprise ; 3 ) in selecting software, 18 indexes and three factors have been put forward including system quality of the software, the fact relating to the software supplier serves, and the fact relating to enterprise, then use ahp to evaluate ; 4 ) in project implementation the evalution flow model on the basis of implementing and the index system have been proposed. the index system include 14 indexes and three respects respect which are control of the goal and plan, quality of the system use, and quality of information. 5 ) performance measurement of erp project is proposed in four respects of balanced scorecard. and according to the characteristic of erp project performance, the result of measurement should been calculated with fuzzy mathematics, then a satisfaction index can be drawn
