宽带干扰 meaning in Chinese
broad band interference
broad-band jamming
broadband disturbance
wide band jamming
Examples
- Assigning serial different address code to different subscribers , useful signal is taken out of the same time slot and frequence , and is transmitted with one share channel . at received end , system makes use of completed address code from sending end to do correlative check and take out useful subscriber signal . the other address code signals are treated as broadband disturbing signal which is removed . in radio environment of existing variable disturbtion and muti - way declining , expand frequence signal ’ s broadband characteristics can improve system performance obviously . cdma mobile telecommunication system has some better characteristics , such as anti - disturbing 、 anti - way declining 、 secrecy 、 capacity 、 utilizing rate of frequence resource and so on , than other mobile telecommunication system
Cdma ( codedivisionmultipleaccess )移动通信系统的技术基础是基于扩频技术的码分多址,通过给不同的用户分配各自特定的地址码序列,将处于相同时隙和频率的用户信号分离开来,采用共享信道方式传输信息。在接收端,系统利用与发送端完全一致的本地地址码对接收信号进行相关检测,提取需要的用户信号,而将其他使用不同码型的信号视为宽带干扰而从中剔除掉。 - It ' s impossible to avoid all interference in the communication system . especially the narrowband interference , which generates much higher power density than the wideband interference does , has a great influence on the quality of the communication , even it can hinder the normal communication
干扰不可避免地存在于通信系统中，尤其是窄带干扰，它产生的功率密度比宽带干扰产生的功率密度高得多，它们对通信质量的好坏，甚至能否进行正常的通信有着极大的影响。
