| 摘要: |
| 本文讨论了GPS干扰源抑制中的多用户检测技术。多用户检测技术将GPS信号中的窄带数字干扰作为多用户信号进行检测,从而在多个干扰源中提取出GPS卫星信号。文中首先给出了CDMA系统中的多用户信号模型,然后具体介绍了3种多用户检测器,并分析了它们的信号干扰比和比特误码率。 |

| Abstract: |
| The technology of multi-user detection(MUD) in GPS interference source suppression is discussed.The multi-user detection technology makes the narrowband interference as multi-user signal to be detected,hence,GPS signal can be obtained from many interference sources.The multi-user signal model in CDMA system is presented and three kinds of multi-user detectors are introduced in detail,then their SIR and BER are analyzed. |
