【摘要】 第三代移动通信技术的长期演进(LTE)系统上行信道采用单载波频分多址(SC-FDMA)方案,拥有较低的峰值平均功率比(PAPR)。首先介绍了LTE的时隙结构和物理资源,然后在3GPP 211协议的规范下,基于LabVIEW仿真了LTE物理上行共享信道过程,生成SC-FDMA信号。最后,仿真了LTE上行链路中SC-FDMA在不同调制方式和系统带宽中的PAPR。更多还原

【Abstract】 SC_FDMA is used in LTE uplink channel and has fairly low PAPR.The slot structure and physical resources of LTE is given first.Then the LTE physical uplink channel process based on LabVIEW is simulated,and SC-FDMA is produced.Finally,the PAPR of SC-FDMA in the LTE uplink with different modulation modes and system bandwidths are simulated.更多还原
