It contributes to the deeper comprehesion of these probability distributions, affords more detailed theoretical basis for further studying and simulating satellite mobile channels, ? theoretical analyses and discussions of the models which are often used in the study of the propagating characteristics of satallite mobile channels are given ; meantime, some discussions on the work of model simulations are also given, ? incorrect derivation of the equality between c. loo model and corazza model in some other papers is pointed out. via the conception of received power, we derivate that in the rural environments these two models really have the equal relationship by the way of theoretical derivation and simulatant fittings. therefore, it is able to use corazza model in studying the characteristics of satellite mobile channels in the rural environments and able to avoid the iterant work of modeling, in order to enhance the efficiency and accuracy of research work, ? detailed processes of simulating lutz model by using matlab6. 0 _ simulink4. 0 and the results of comparisions are given
本文包含有以下的主要內容： ?對衛星移動通信通道傳播特性研究中常用的三個概率分佈給出了詳細的推導過程；以便對這幾個在衛星移動通信通道傳播特性的研究中常用的概率分佈函數有更深的理解，對進一步研究衛星移動通信通道傳播特性和對通道的建模提供了更為詳盡的理論基礎； ?對衛星移動通信通道傳播特性的研究中常用的通道模型進行了理論上的分析和討論，並對衛星移動通信通道建模的研究工作提出了一定的看法； ?指出了以前的文獻中關于c . loo模型和corazza模型的等同性的證明錯誤；並從接收信號功率的角度出發，通過理論推導及模擬曲線擬合重新證明了在鄉村環境下，這兩個模型的確是具有等同性的；從而在對鄉村環境下的衛星移動通信通道傳播特性進行研究時，可以只採用corazza模型來對實際的通道進行建模，這樣可以避免重復的建模工作並提高研究工作的效率和準確性； ?給出了lutz模型在matlab6 . 0 _ simulink4 . 0環境下的軟體模擬實現的詳細過程和整體模擬測試的對比結果，保證了該模型在硬體實現時的可靠性和可行性，從而可以將它們應用於指導模型的硬體模擬實現並可以降低硬體實現時的風險。In this paper, according to the theory of signal detection and estimation, the optimal receiver pattern of pn code signal is introduced and theoretically, the relation curve of the probability of the correct detection with the input s / n ratio under the different probabilities of false alarm is illuminated
根據信號的檢測和估計理論，文中分析了數字相關器實現偽碼信號接收的最佳模型，從理論上計算了在不同的虛警概率下，檢測概率隨輸入信噪比的變化曲線，並分析了doppler效應對偽碼相關接收的影響。3. characteristics to point out the essence of opportunity cost is return rate of factors, so use the opportunity cost of factors to do the benefit - cost account of agriculture products is in line with the principle of market - economy. to suggest improving the ways of the benefit - cost account of agriculture products, and put forward a new system of he benefit - cost account of agriculture products ; to calculate the shadow prices of agriculture production factors by using stochastic frontier production function and marginal productivity theory, especially acquire the shadow prices of the agriculture land ; to do the principle analysis on the supply - demand mechanism, and suggest the supply and demand curves of china agriculture production factors ; to prove the applicability of using stochastic frontier production function to research the product ion cost of agriculture products
本文研究的創新和特色之處為：指出要素機會成本的實質是要素的投資報酬率，從而認為以要素機會成本作為農產品成本收益核算的基礎概念符合市場經濟原則；提出以生產要素的機會成本概念為計價原則，以改進中國農產品的成本收益核算方式，據此提出符合市場經濟原則、體現完全生產成本的中國農產品成本收益核算項目體系；以隨機前沿生產函數方法和要素邊際生產力理論為邏輯框架直接測算中國主要農業生產要素的價格，特別時土地要素的價格；對中國農業生產要素的供給和需求機制進行理論分析，給出中國農業生產要素的供給、需求曲線；在理論上論證用隨機前沿生產函數技術研究農產品生產成本問題的適用性。
