OFDM-CDMA是继第三代移动通信之后移动通信技术中的新热点,这里分别对单用户检测器,解相关检测器,线性最小均方(MMSE)检测器和采用最陡下降常模算法(SDCMA)的盲多用户检测器在OFDM-CDMA系统中的误码率性能进行了比较和分析。
OFDM-CDMA is a new hot spot in the mobile communication technology after the third generation of mobile communication. Here, the single-user detector, decorrelation detector, linear least mean square (MMSE) detector and the steepest descent normal mode algorithm SDCMA) blind multiuser detector in the OFDM-CDMA system bit error rate performance were compared and analyzed.
