摘要
为了消除TD-SCDMA中多址干扰和符号间干扰,提出了多用户联合检测传输模型,在此基础上设计了多用户联合数据检测算法,并推导了迫零准则和最小均方差准则进行数据检测,然后就TD-SCDMA系统应用环境进行了仿真和分析.仿真结果表明多用户联合检测技术在TD-SCDMA系统中具有优越性和良好的应用前景.
A model of multi-user joint detection in TD-SCDMA for eliminating multiple access interference and intersymbol interference was presented.The multi-user data detection algorithms were designed which were based on MMSE or ZF criterion.Through simulation and analysis in the TD-SCDMA system,multi-user joint detection technology demonstrated its superiority and application prosperity in TD-SCDMA.
