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。 -
In order to elaborate the app licability of osl to loess, especially single aliquot regenerative protocol ( sar ), involving stimulation of the same disc with an infra - red laser diode followed by blue leds to polymineralic fine - grains of loess, such explanations as light bleaching, preheat, anomalous fading, prior - ir exposure were investigated in this paper. for drawing adequate coarse grains from loess, quartz and feldspars, as well as loess, were etched by hydrofluoric acid and fluorosilicic acid. the sequence of ages of holocene loess in weihe rivier basin has been established by single - aliquot ( sar ) and multiple - aliquot using fine - grains and sar using coarse - grains
