摘要

考虑了双选择性(时频选择性)信道下DS-CDMA的多用户检测问题，提出了时变多用户检测器(TV-MUD)来解决该问题。利用基展开模型(BEM)对双选择信道和TV-MUD进行建模，推导出TV-MUD的BEM系数作为双选择信道BEM系数函数的封闭表达式。我们使用的标准是均方误差符号。

Time-varying multiuser detection for DS-CDMA in doubly-selective channels

The problem of multiuser detection for DS-CDMA in doubly-selective (timeand frequency-selective) channels is considered, and a time-varying multiuser detector (TV-MUD) to solve this problem is proposed. Using a basis expansion model (BEM) to model the doubly-selective channel and the TV-MUD, we derive a closed-form expression for the BEM coefficients of the TV-MUD as a function of the BEM coefficients of the doubly-selective channel. The criterion we use is the symbol mean-square error.
