摘要
提出了一种新的基于多载波调制技术的多用户检测器。分析了检测器的干扰相消原理 ,并给出了误码性能。该检测器具有结构简单 ,计算复杂度低 ,其性能较传统的多用户检测器性能有较大幅度的提高 ,在收发频差、定时为零的情况下 ,达到了单用户情况下检测器的性能。
A new synchronous multi-user detector of DS/CDMA is proposed in this paper, which is based on multi-carrier wave modulation technology. The principle of this detector is analyzed and the performance of the detector is given . This new detector has simple configuration and low complexity of calculation. Compared with conventional multi-user detectors, its performance has been obviously improved and it has the same performance as single-user detector when frequency difference of transceiver and timing is zero.
