遍歷測度 的英文怎麼說
中文拼音 [biànlìcèdù]
遍歷測度
英文
ergodic measure-
Though maximum likelihood detection ( mld ) can obtain optimum detection performance in mimo communication systems, the ergodic search increases the complexity exponentially with the number of the antennas, which lead to implemental difficulty
在mimo通信系統信號檢測中，最大似然檢測（ mld ）可以獲得最佳的誤碼性能，然而遍歷式搜索方式使得mld的計算復雜度隨天線數呈指數形式遞增，在實際系統中，往往難以實時實現或者不能實現。We define a type of hyperbolicity on the full measure invariant set which is given by the oseledec ' s multiplicative ergodic theorem and prove that the system has the lipschitz shadowing property on it
對于由oseledec乘法遍歷定理得到的滿測度（ fullmeasure ）不變集定義了雙曲性，並證明了系統在這個不變集上具有lipschitz跟蹤性。Ergodicity on ergodic measure product
關于遍歷測度乘積的遍歷性The invariant measure and ergodicity of markov chains in random environments
隨機環境中的馬氏鏈的不變測度與遍歷性Ergodicity and symmetry of such processes are also investigated and solved. equilibrium distributions are then established. kendall ' s conjecture for the processes is proved to hold
討論並解決了過程的遍歷性和可配稱性，求出過程的遍歷測度，最後證明了kendall猜想對廣義單瞬時生滅過程也成立。It can be used in any complex environment, can locate all paths from transmitter to receiver which avoid redundant calculation, and it is a standard 3 - d forecast model ; in addition, it is a point to point ray tracing method based on specular theory which do n ' t carry out the receive test ; furthermore the model adopt the reverse arithmetic which exert the tree concept in data frame and establish a virtual fountain tree permanently, the proagmme can back - search the virtual fountain tree when it is running. these operation increase the calculate speed and it result in the higher receive efficiency and precision. the thesis design a programme to compare the prediction results based on ray tracing method of virtual fountain tree between the measurement results and prediction results based on the other transmittion models. the comparsion result indicate the new model is a better model
它可應用於任何復雜的傳播環境中，能找到發射機到接收機之間的所有電波傳播路徑而無須冗餘的計算，是一種準三維的預測模型；另外，從本質上講，它仍然是一種基於鏡像理論的點對點的射線跟蹤法，所以它無須進行接收測試；而且由於採用了反向演算法，運用數據結構中多叉樹的概念，先確定需要計算的場點位置，找出所有能從源點到達場點的射線，並且可一次性建立一個虛擬源樹，以後每次的計算只要通過對該樹進行後序遍歷即可，大大提高了運算速度，因而有較高的接收效率與精度。本文對該模型進行了相應的模擬，並將其預測結果與實測結果以及基於cost231經驗性模型和基於強力射線跟蹤確定性模型的預測結果進行了比較，結果表明了該模型的優越性。The idea behind it is to approximate the object with a simpler bounding volume that is a little bigger than the object. in building hierarchies on object, one can obtain increasingly more accurate approximations of the objects. so during traversing bounding volume hierarchy, it speeds up collision detection by prune away primitive pairs, which will not intersect clearly though rapid intersection test between bounding volumes and just deal with those whose bounding volume is intersected
層次包圍盒方法是解決碰撞檢測問題固有時間復雜性的一種有效的方法，它是用體積略大而幾何特性簡單的包圍盒來近似地描述復雜的幾何對象，並通過構造樹狀層次結構來逼近對象的幾何模型，從而在對包圍盒樹進行遍歷的過程中，通過包圍盒間的快速相交測試來及早地排除明顯不可能相交的基本幾何元素對，而只對包圍盒重疊的部分元素進行進一步的相交測試，以提高碰撞檢測的速度。Uniformly weak ergodicity of markov chains in random environments
鏈的不變測度及遍歷極限The main results are as follows : ( 1 ) there exists an one - to - one correspondence between the invariant measures of mutually topologically equivalent semi - flows, and there also exists an one - to - one correspondence between the invariant measures of a continuous map and that of its suspended semi - flow
我們證明了如下結論： （ 1 ）在拓撲等價的連續半流的不變測度之間以及在連續自映射及其扭擴半流的不變測度之間存在一一對應，並且這對應保持遍歷性。分享友人
