In this paper the interfering effect of FM signal on a direct sequence(DS) spread spectrum system is analysed, and the formulae are proposed, which can be suitable for both narrow-band and wideband FM signals. The concept of "equivalent noisy power spectral density" is introduced in this paper. So long as the power spectral density of the interfering signal is known, it may be changed into ths "equivalent noisy power spectral density" and hence the bit error probability of the DS system will be calculated....

In this paper the interfering effect of FM signal on a direct sequence(DS) spread spectrum system is analysed, and the formulae are proposed, which can be suitable for both narrow-band and wideband FM signals. The concept of "equivalent noisy power spectral density" is introduced in this paper. So long as the power spectral density of the interfering signal is known, it may be changed into ths "equivalent noisy power spectral density" and hence the bit error probability of the DS system will be calculated. Using this method, we can easily obtain the DS system's reception performance interfered by a FDM-FM or TV-FM signal.

本文分析调频信号对直扩系统的干扰效应,导出了既能适合于窄带调频又能适合于宽带调频情况的干扰计算公式。文中提出等效噪声功率谱密度的概念。只要知道干扰信号的功率谱密度函致,即可将其折算为等效噪声功率谱密度,从而算出直扩系统的误码率。采用此法,可方便地分析出FDM-FM或TV-FM信号干扰下的直扩系统接收性能。

In this paper, the coherent scattering model is used to study on dependency relationship between chaff cloud and its spatial distribution in the outer space. Curves and curved surfaces between scattering cross section of some typical distribution chaff cloud and its spatial distribution parameters are given. Experiment results show that chaff cloud′s scattering cross section greatly varied with different spatial distribution form. In some instances, variation of chaff cloud′s scattering cross section can reach...

In this paper, the coherent scattering model is used to study on dependency relationship between chaff cloud and its spatial distribution in the outer space. Curves and curved surfaces between scattering cross section of some typical distribution chaff cloud and its spatial distribution parameters are given. Experiment results show that chaff cloud′s scattering cross section greatly varied with different spatial distribution form. In some instances, variation of chaff cloud′s scattering cross section can reach 8~12dB. Significantly, the effective scattering cross section of chaff cloud can be increased by optimizing the distribution of chaff cloud, then interfere effect can greatly improved.
