| 4. | Martin : oh , it ' s no big deal . i broke it bungee jumping 马丁:噢,没什么大不了。我玩笨猪跳时弄断的。 |
| 5. | Spread spectrum communication technology can be classified into four catalogs : direct sequence spread spectrum , frequency hopping , time hopping and chirp 扩频技术种类较多,主要包括直接序列扩频、跳频、跳时和线性调频。 |
| 6. | Diagnosising energy and angular momentum chang of subtropical high when it actually bounce northwards , we get three ways of chang of angular momentum and provide basis of forcasting of subtropical high 结合实际诊断了解副高北跳的能量和角动量等变化情况,得到北跳时角动量补偿三种方式等,为短期预报副高北跳提供依据。 |
| 7. | In the paper we study the drift criterias of these forms of stability . pdmp was introduced by davis . the distribution funtions of davis " must be absolute continuity . guoxin liu first introduced the pdmp with discrete part and our results are for the pdmp with discrete part 本文利用drift有关的判别法来给出这些性质的判别条件、 pdmp最初是由davis引入,其引入的pdmp的首次跳时的分布函数要求必须是绝对连续的,本文是针对刘国欣推广的pdmp模型。 |
| 8. | Then we introduce pulse position modulation ( ppm ) using pn code and analysis its multi - access performance , system capacity and power spectrum density . on the basis of those analyses , we study the pulse shape and the anti - jamming ability of the system . at last , multiple access with pseudochaotic time hopping is introduce 本文首先阐述了uwb脉冲通信系统的基本原理,重点介绍了用伪随机码跳时的ppm (脉冲位置调制)调制,分析了他的多址性能、系统容量和功率谱密度,在此基础上研究了改进性能的发射信号形状和系统抗干扰能力,最后介绍了伪混沌码跳时的多址方式。 |
