| 摘要: |
| 在DS—CDMA中，频带内即使有一个窄带干扰存在，所有用户都会受影响，所以希望在DS—CDMA信号检波前除去窄带干扰。研究了利用干扰信号的窄带性和载波频率的事前信息的窄带干扰去除方案，以及对DS—CDMA信号的高功率窄带干扰的去除方法。 |

| Narrowband Interference Rejection Technique for DS-CDMA Systems |
|
| () |
| Abstract: |
| In a DS-CDMA system,even if a narrowband interference(NBI)exists,all users will be influenced,so it is hoped to remove the NBI before detection of DS-CDMA signal.In this paper,a scheme for removing interference by using narrowband's quality of interference signal and information of carrier frequency is studied,and the high power NBI rejection method for DS-CDMA signal is discussed. |
