- 提高卫星通信信道传输效率的新途径本 文 结 合 V SAT卫星通信系统设计中涉及卫星通信传输技术极为重要的 信道编码与调制解调方式，探讨了各种新型的卫星信道编码与调制解调技术， 它们的原理及在卫星通信中的应用。在数字调制中，信号传输质量主要取决于 比特差错率BER (Bit Error Rate)，因此要尽可能采用相同的每比特信号能量与 噪声功率谱密度比(Eb/N.)的条件下，BER低的调制方式，以节省卫星功率 另外频带利用率要尽可能的高，以节省宝贵的卫星频带。本文还对各种

- 还有一个缺陷就是在只知道密文 x 及公钥（n,e）的情况下，只要将 (x^e) mod n 所得余数 s 再不断地循环操作 s = s^e mod n，此运算不断地循环 e 次之后，很多情况下都可以循环出原文，只是计算量过余多一些罢了。不过有不少情况下，根本都无须循环 e 次，不过对于1024位的 n 级别来说，e 也是一个相当大的数值，所以循环密文的余数以解得原文是有些不现实。 以上内容仅供参考，如有不实，请予更正-there is a defect in only know that the

MT-001-SNR
- 接触ADC或DAC时您一定会碰到这个经常被引用的公式，用于计算转换器理论信噪比 (SNR)。与其盲目地相信表象，不如从根本上了解其来源，因为该公式蕴含着一些微妙之 处，如果不深入探究，可能导致对数据手册技术规格和转换器性能的误解。记住，该公式 代表的是完美N位ADC的理论性能。您可以比较ADC的实际SNR与理论SNR，看看二者有 何异同。-Contact ADC or DAC, you will encounter this oft-quoted formula used to
