adaptive tests 解釋
自適性考試
  1. Test results show that under 2 - tone test in 5mhz tone spacing, the power amplifier system achieves - 50dbc imd3 with 20w output power, improved 20db in imd3 compared with the one without linearity. estimated value of aclr comes to 53db, which satisfies the 3gpp requirement for wcdma base - station transistor. further tests with alterative input power indicate a steady suppression to the imd3 controlled by the adaptive system

  3. Afterwards, in order to decrease the contradiction between the more complex and mass remote sensing image data and relatively slow speed of information extraction, an improved sfim image fusion method is proposed. this modified algorithm is on the base of sfim fusion technique, combines ihs method and sfim method and then replaces the former mean filter by an adaptive weighted mean filter. compared with the results of several common fusion techniques through a set of simulation tests between multispectral images and panchromatic images, it is proved that the new method can get an excellent result for the aim of improving spatial resolution while preserving the spectral information of multispectral images

    論文的主要工作和成果包括:在像素層,論文研究了多傳感器數據融合理論及遙感圖像預處理的過程和步驟,歸納了多源遙感圖像像素層融合的常用演算法,並針對目前遙感數據呈海量化、復雜化這一發展趨勢同遙感信息提取的能力和效率滯后這一矛盾,在sfim演算法的基礎上,將ihs變換與sfim相結合,將原演算法中的均值濾波器改進為自適應加權均值濾波器,提出了一種改進的sfim演算法,通過對一組多光譜圖像和全色圖像的雙傳感器融合模擬對比試驗,證明了該演算法在保持原多光譜圖像光譜信息的同時,能夠有效提高融合圖像的空間分辨能力。
  4. As an up - to - date applied tech, ecu hardware - in - loop simulation system ( ecu hilss ) can be regarded as a tool with integrated software and hardware, which is adaptive for real - time simulation. during debugging, the hilss is connected to ecu directly as a virtual engine, receiving the control from the ecu and sending out the homologous running message of the engine, which reduce the tests and cost of all kinds. besides, operators are provided with a convenient way of conditioning and observing the whole system because of its software controlled mechanism of imparting information

    作為一門新興的應用技術, ecu硬體在環模擬系統( ecuhilss )可以看成是一套軟硬體集成的實時模擬工具,在對外部ecu系統進行調試時,它作為虛擬發動機的載體直接與ecu系統相連,接受ecu的控制調節,並向ecu提供相應控制下的發動機實時運轉工況信息,這樣就相應地減少了臺架試驗,在節省各種人力物力的同時縮短了調試時間;此外由於hilss是通過編制軟體來實現各種信息傳遞,它能給操作者提供方便友好的調節觀測環境,從而大大增強ecu調試過程的靈活性和可靠性,消除由於某些試驗因素可能導致的危險性。
  5. An active vibration control system for the piezoelectric flexible adaptive truss structure was set up for real - time computer active vibration control experimental tests
