- W3143585728 abstract "活动 WiMAX (为微波存取的世界范围的互操作性) 空气接口采用直角的频率分割多重存取(OFDMA ) 为它的 uplink (UL ) 和 downlink (DL ) 到的同样多重的存取技术改进 multipath 性能。所有 OFDMA 基于的网络象活动 WiMAX 一样，经历高 peak-to-average 力量比率(PAPR ) 的问题。高 PAPR 增加 analog-to-digital (A/D ) 和 digital-to-analog (承兑交单) 变流器的复杂性，并且也减少 RF high-power-amplifier (HPA ) 的效率。在这个工作，新 zadoff-chu 矩阵变换(ZCMT ) precoding 基于随机的交叉直角的频率分割多重存取(OFDMA ) 系统在活动 WiMAX 为 PAPR 减小被建议系统。系统基于 precoding 有在印射的副载波前的 ZCMT precoder 的星座符号。建议系统的 PAPR 与 root-raised-cosine (RRC ) 被分析塑造使带外的放射低并且满足传播光谱面具要求的脉搏。模拟结果比 hadamard 变换(WHT ) precoded 随机交叉 OFDMA 系统，常规随机交叉 OFDMA 系统的证明建议系统让更好的 PAPR 增加。系统的 Symbol-errorrate (重量的单位) 性能比常规随机交叉 OFDMA 系统，随机与 WHT 交叉 OFDMA 系统的也好。在 PAPR 的好改进显著地减少费用和传输器的复杂性。" @default.
