| 摘 要： | 将经过延时编码的联合检测(joint detection,JD)算法用于多用户MIMO MC-CDMA下行系统.仿真实验表明,与VBLAST检测算法相比,延时编码的JD检测算法性能良好,并能应用于VBLAST无法应用的接收天线数目少于发送天线数目的MIMO系统.该文还分析了2发2收时用Alamouti编码来代替延时编码的误码率性能.

| Abstract: | In this paper,a joint detection(JD) technique with delay coding is used for the downlink of multi-user MIMO MC-CDMA systems.Compared with VBLAST downlink signal detection,JD detection provides better performances and can be applied in case the number of receiving antennas is less than transmitting antennas.The paper also studies bit error rate of the system using Alamouti coding with two transmitters and two receivers. |
