摘要 功率控制技术是WCDMA系统中克服“远近效应”、降低多址干扰(MAI)、保证链路质量、提高系统容量的关键技术。多用户检测技术是消除MAI的有效手段。本文分析两种技术的工作原理,指出二者之间的关系,探讨在WCDMA应用中结合使用两种技术的可行性和方法。 Power control is the key technology in a WCDMA mobile system to conquer the near-far effect and reduce multi-address interferes so that can ensure the communication quality of hnks and improve the system capability. Multi-user detection is an effective means of eliminating multi-address interfere. This paper analyzes the principle of their operation and relationship between them; further discuss the feasibihty and method to unite power controlling and multiuser detection in a WCDMA system.
