power of signals meaning in English
信号功率
Examples
- Moreover , the saturation characteristic of raman fiber amplifier is also one of the important parameters and the total power of signal light input into the fiber is limited by it
另外，饱和特性也是光放大器的重要指标之一，它限制了可以输入光纤的总信号光功率。 - Secondly , the paper researches blind estimation of signals parameters , including the carrier frequency , signal to noise ratio and symbol rate of digital modulations . thirdly , with the combination of parameters from early studies on the decision theory , a set of robust feature parameters are extracted from signal power spectrum and the power spectrum of the second and fourth power of signal . based on these parameters , the proposed scheme is able to recognize 12 types of common used modulations , namely ask 、 2fsk 、 msk 、 4fsk 、 psk 、 qpsk 、 / 4qpsk 、 8psk 、 am 、 dsb 、 ssb 、 fm
接着,对信号功率谱、平方谱及四次方谱进行研究,针对通信中常用的调制方式,结合前人提出的基于决策理论中的特征参数,设计了一组对信噪比和信号调制参数不敏感的分类特征参数,利用上述参数完成了一种基于信号频域的识别方法,可以对ask 、 2fsk 、 msk 、 4fsk 、 psk 、 qpsk 、 / 4qpsk 、 8psk 、 am 、 dsb 、 ssb和fm这12种常用调制方式进行识别。 - When blanket jamming is used , the more the ratio between the power of jamming and the power of signal , the less detection probability of the radar is . the effect of distributed jamming mainly depends on the total power . after distributed , the randomicity of distance and phase of jamming source bring difficulties to analysis
对压制式干扰来讲,干信比越大,雷达的发现目标的概率就越小,由于分布式干扰的干扰效能在于其合成功率,在分布式干扰单元分布之后,各个干扰源与被干扰对象之间的距离的不确定性,带来了干扰信号相位的不确定性,增加了分析干扰效能的复杂度。
