【摘要】 提出一种用于同步ＣＤＭＡ移动通信系统的新型多用户检测器———正交判决反馈多用户检测器，并将其与一般的判决反馈检测器作了对比．结果表明，两种检测器具有同样的抗远近效应性能，但正交判决反馈多用户检测器的结构简单，计算复杂度也得到简化．更多还原

【Abstract】 A novel multiuser detector for synchronous CDMA communication systems—orthogonal decision-feedback multiuser detector is proposed in this paper, which is compared with the original decision_feedback detector. It is shown that the two kinds of detectors are similar in aspect of cancelling near_far effect but the orthogonal decision_feedback multiuser detector has a simpler structure and a simplified algorithm complexity.更多还原
