| 摘 要： | 直接序列扩频信号在军事通讯中具有广阔的应用前景。针对直接序列扩频通信系统扩频码本身的特点,从理论上推导得出了直接序列扩频信号的时频特性和参数估计。分析了噪声干扰技术和回波模拟技术。通过计算机仿真,对比了样式相同而不同干扰功率情况下直接序列扩频通信误码率,其仿真结果验证了理论推导的正确性。 |
| 关 键 词： | 直接序列扩频 时频谱特性 干扰 |

| Abstract: | Direct-Sequence Spread-Spectrum signals(DS-SS) have great value in the implement of military communication systems.Based on the characteristics of PN codes of DS-SS,the Winger distribution is used to deduce the features of Time-Frequency and to estimate parameters.Through simulation,the error rate of DS-SS under the same style and different power is compared.The result shows the method is valid. |
| Keywords: | direct sequence spectrum time-frequency spectrum characteristics jamming |
