| 4. | The application of spread spectrum technology can increase dimension of signal in order to improve signal power and achieve code gain 扩频技术的应用可以增加信号维数以提高信号功率也可获得编码增益。 |
| 5. | The amazing character of the quantum capacity of gaussian channel is that planck constant h takes over the place of input power restriction of classical capacity 高斯信道量子容量的迷人特征是普朗克常数h取代了经典容量中输入信号功率限制条件的位置。 |
| 6. | Because the synchronization error is independent of information signal , the power and frequency of information signal can be equivalent to that of chaotic signal 由于同步误差与信息信号无关,从而在增大信息信号功率的同时允许其频率与混沌信号的频率相当。 |
| 7. | The drawbacks of the former one are that higher power is required to reach a satellite at that distance and a substantial round trip signal delay is inevitable 前者的缺点是由于距离较远因而要求较大的信号功率以及存在较长的信号延迟,而后者则由于卫星数目巨大而费用昂贵。 |
| 8. | Contrast to traditional jamming , distributed jamming have it ’ s own characteristic . this kind of jamming will be more and more important in ew ( electronic warfare ) 说明分布式干扰无论在信号形式多样化、提高信号功率等方面与传统大功率干扰机相比,都会在现代信息战中占有越来越重要的位置。 |
| 9. | The method using the part imitate extract the continuous spectrum of the signal spectrum , than extract line - spectrum from the relatively flat line - spectrum by subtract it from the former spectrum 该方法利用分段拟合方法拟合出信号功率谱的连续部分,从原始功率谱中减去连续谱得到拉平的线谱分布,然后进行线谱特征提取。 |
| 10. | In new system the error pa can also amplify the original signal , so the performance of whole amplifier system increases . since rf predistorters used in the new system , the linearity and power efficiency can be enhanced 该技术改变了误差通路中的信号特性,使误差放大器也输出有用信号功率,提高了整个放大系统的性能。 |
