| 摘 要： | 空间同频干扰在无线直放站工程现场普遍存在,传统的射频滤波器技术无法在频域上解决此问题,因而容易引起直放站自激.文章运用了一种数字化干扰自适应消除技术,其效果相当于将直放站的空间隔离度提高了30 dB以上,从而可以有效解决以上问题.

| Abstract: | Commonly existing in wireless repeater project site,space co-frequency interference can hardly be eliminated by the traditional RF filter technology in the frequency domain,resulting in self-excitation in the repeater.In this paper,a digitalized adaptive interference cancellation technology is applied to solve this problem with an effect equivalent to the improvement of the repeater space isolation degree by over 30 dB. |
