The analytical results show that the image distortions from the watermark are spread throughout the whole image and are spread into the three channels of a color host image by a hypercomplex inverse Fourier transform. So the proposed watermarking algorithm can realize a good combination for the imperceptibility and security of the watermark.

随辐照时闻的增加，温度的升高，其温度涨落的幅度基本保持不变，这一持性是由不锈钢的热学参数如热传导率、热扩散率随温度变化的规律所决定的。

Multiple antenna arrays are often used to overcome the effect of channel fading which is caused by multipath interference. In chapters 4 and 5 ,we derive spatial correlation equations of ULA ,UCA and CRA for two types of angular spread distributions (uniform distribution and truncated Gaussian distribution).We also compare the difference between these antenna arrays by showing the bit error rate simulation results and discuss the relationship between BER and spatial correlation. In a multi-user mobile radio environment , we present simulation results to show that adaptive MBER algorithms have better performance than the traditional MMSE algorithm.

多天线阵列常被用来克服多重路径干扰导致通道衰减的影响，我们对各种天线阵列架构进行比较，在第四、五章中推导出ULA、UCA与CRA个别对两种角度扩散机率密度分布的空间相关性函数，由实际实验模拟的位元错误率图形比较天线阵列间的差异，并讨论位元错误率与空间相关性之关连，在多用户端行动通讯环境下，我们也由模拟验证可适性MBER演算法，会比传统MMSE准则有更好的效果。

Experiment result indicates that the RFHP has greater thermal diffusivity, and can reduce junction-to-case thermal resistance of the module. When power density is 176W/cm^2, the temperature difference on the condensation section is within 3℃. The longer time period for the chip to reach the same temperature during RFHP module start-up can avoid power uprush and raise the ability of resisting thermal impact.

结果表明：与铜基板相比，径向平板热管具有更高的热扩散能力，可降低模块的结壳热阻；热管冷凝面具有良好的等温性，当芯片功率密度为176W/平方公分时，热管冷凝面的温差在3℃以内；热管模块启动过程中芯片达到相同温度需要的时间长，有利于克服功率"飙升"和提高功率器件抗热冲击的性能。
