不完全功率控制技术抗多址干扰研究

Study On Canceling Multi-access Inference With Imperfect Power Control

本文从抗多址干扰的角度阐述了CDMA中系统功率控制技术的原理，研究了如何求不完全功率控制下的平均设码率的上限和下眼，总结了功率控制技术抗多址干扰方法的缺点，并在文章的最后介绍了新式抗多址干扰技术。

In this paper, we descibe the theory of the technique of power control, in the term of canceling multiple access inference. We have studied on how to calculate the upper and the lower boundson the average Probaility of error of CDMA system with imperfect power control. The defects of CDMA system with Power control are sfored. In the end, some new techniques ofanti - multiuser - inference are referred. summarized. Inthe end,some new techniques of anti - multiuser - infernce are referred.
