摘　　要：TD-SCDMA系统采用短码,其抗干扰能力较差,但同时码短具有运算量小等优势,可以实现多用户检测,消除同频干扰。目前基于单小区的联合检测技术已经在全网进行了应用,但是对于以邻小区的干扰为主CDMA系统来说,应在本小区实现联合检测的同时重点关注邻小区的干扰,并采取相应技术和措施进行消除或降低,以不断改善TD-SCDMA网络质量,提高用户感知。多小区联合检测技术(MCJD)是TD-SCDMA系统重要的干扰消除技术之一,本文从引入背景、技术原理、操作流程、应用条件及应用场景等几方面进行详细介绍,最后总结出具体的应用建议和原则。TD-SCDMA system using a short code,its poor anti-interference ability,but a short code with computational and other advantages,multi-user detection can be achieved,eliminating co-channel interference.Currently based on single cell joint detection techniques have been applied in the whole network,but to adjacent cell interference-based CDMA system,the district should implement joint detection in the same time focus on adjacent cell interference,and appropriate technologies and measures taken to eliminate or reduce to continuously improve the quality of TD-SCDMA network,improve user perception.Multi-cell joint detection technology TD-SCDMA system is an important interference cancellation technologies,this paper introduces the background,technical principles,operating procedures,application conditions and scenarios described in detail in several areas,concluded a specific application of recommendations and principles.
