Based on piecewise linear model, this paper proposes an estimation method that first estimates the slope of linear variant and the channel impulse response at the middle time of the current ofdm symbol using pilot sequences, and then estimates the whole channel impulse response through the estimated parameters
該演算法首先利用導頻序列估計出當前ofdm符號間隔內通道線性變化的斜率和中間時刻通道的沖激響應值,然後根據線性模型利用估計出的參數得到當前符號間隔內所有時刻上的通道沖激響應。( 2 ) develop an urban microscopic traffic simulation system, which involves vehicle generation model, network model, traffic regulation model, signal control model, vehicle action model, route choice model and intersection turning model. ( 3 ) realize and research the method that signal cycle and phases are assigned by the traffic need. when vehicles od is known, this method can be used to decide the maximum traffic capacity of signal - controlled intersection and the evaluation reference of current control method
模型中充分考慮了鄰道車輛對駕駛行為的影響及駕駛員的反應延遲,使模型更符合真實情況; ( 2 )開發了城市微觀交通模擬系統:該系統包括車輛產生模型、路網模型、交通規則模型、信號燈控制模型、車輛行為模型、路徑選擇模型、路口轉向描述模型; ( 3 )在模擬應用中實現並研究了信號燈周期及其相位按交通需求動態分配的方案,提出該項模擬可用於確定在已知od下,信號燈控制路口的最大通行能力,並可作為現有控制方案的評估依據。The main works and innovations of this thesis are as follows : ( 1 ) based on the oversampling of ofdm frequency response, this paper proposes a channel estimator which combines the comb - pilot - tones partitioning and the fourier transform with the same pilot symbol samples
具體而言,主要有以下六個方面的工作和創新點: ( 1 )利用在ofdm系統中通道的頻域響應是過采樣的特性,提出了在頻域內用均勻梳狀分佈的導頻符號和與導頻符號數相同點的傅里葉變換相結合的通道估計方法。Second, by combining theories of strength of laminate with ga, a new gradient free optimization method with new code strategy is discussed. the representation itself does not change the nature of the problem, but effects the searching efficiency of the algorithm. so the representation of the parameters to be optimized is a very important factor and the new code strategy is also easy used with crossover operator and variation operator in ga applications
其次,本文根據層合板優化設計的具體問題提出了一種符號編碼方式,雖然優化參數的基因編碼表達方式並不能改變優化問題的本質,但是不同的編碼表達方式對于遺傳演算法搜索的效率和最終的優化結果有著重要的影響,因此優化參數的基因編碼表達是遺傳演算法應用於工程問題中非常關鍵的一步。What the practical problems is often gotten is a single variable time series which has a time interval of t, reflect by a lot of interactive physics factor, containing the mark of all variates participating in movement, traditional time series analysis is to analyse going from this array to the form directly it ' s time develops, one dimension analysis loses useful information, the characteristics of phase space reconstruction method is to construct one dimension scalar quantity to high dimension vector, prop the geometry space of the state, show all dynamical information of system in phase space. the characteristic that just constructs again according to the phase space in this text, analyse the time series of responding, use the relevant knowledge of symbol dynamics and reconstruct phase space, put forward a kind of relation degree analysis method of the systematic mathematics model which has theory basis, so reach the correction of calculation mathematics model, make it accord with the actual systematic state
實際問題中常常得到的是一個時間間隔為t的單變量的時間序列,它是許多物理因子相互作用的綜合反映,蘊藏著參與運動的全部變量的痕跡,傳統的時序分析是直接從這個序列去形式地分析它的時間演變,一維分析必然喪失許多有用信息,相空間重構方法的特點是把一維標量數據構造成高維矢量,支起狀態的幾何空間,在相空間中展示系統全部動力信息。本文正是根據相空間重構的特點,對響應時間序列進行分析,利用符號動力學、重構相空間等方法,提出一種有理論依據的系統數學模型關聯度分析方法,從而達到修正計算數學模型,使其更符合實際系統狀態的目的。分享友人
