And then facing the problem of the channel estimation of the adaptive modulation system, we conclude out the channel estimation algorithms on maximum likelihood ( ml ) estimation and maximum a posteriori ( map ) estimation under the condition of flat fading channel and selective fading channel in detail. to meet flat fading channel, we simulate the relationship of the ratio between the error covariance in map estimation and ml estimation and pilot symbol message length. the conclusion can be drawn from these results
接著，對自適應調制系統中的通道估計問題難點，詳細推導了平衰落通道條件下和選擇性衰落通道條件下最大似然（ ml ）估計和最大后驗概率（ map ）估計演算法，針對平衰落通道，我們模擬了map估計和ml估計的方差與導頻符號長度的關系，模擬結果表明，錯誤方差受
多譜勒頻率的變化影響最大，並且對實際的自適應調制系統，導頻符號長度的取值
超過20個符號長度時， map通道估計明顯優于ml通道估計。
But this additional food is only obtained by a great additional amount of labour ; so that not only an agricultural has much less leisure than a pastoral population, but, with the imperfect tools and unskillful processes which are for a long time employed ( and which over the greater part of the earth have not even yet been abandoned ), agriculturists do not, unless in unusually advantageous circumstances of climate and soil, produce so great a surplus of food, beyond their necessary consumption, as to support any large class of labourers engaged in other departments of industry

In this article, starting from the biggest objective factor - the unipolar world order with the united sates standing out of all the other powers - and the biggest subjective factor - the traditional diplomatic thoughts of the united states, the author tries to analyze various disagreements and arguments about the united nations in america, especially between the whitehouse and the congress, so as to bring to light the reason why the united states ca n ' t have or implement a stable and clear - cut un policy. by trying to locate the united nations in the global hegemon strategy of the united states, the author put on exposure the essence of america ' s un policy : the united states is striving to lead and dominate the united nations and using it as a means to materialize its global hegemon dream
