摘要

单载波频分多址(SC-FDMA)是第三代合作伙伴项目长期演进(3GPP-LTE)推荐用于下一代无线通信系统上行传输的技术。由于峰值平均功率比(PAPR)是任何类型上行传输的主要问题之一，本文提出了盲选择映射技术作为一种降低PAPR的方案。仿真结果表明，所提出的B-SLM技术的PAPR性能与对流选择映射C-SLM的PAPR性能大致相同，但B-SLM技术提供了带宽的减少，而不会显著降低误码率(BER)性能。研究了固态功率放大器(SSPA)对SC-FDMA系统性能的影响。

Impact of power amplifier non linearity on blind selective mapping for SC-FDMA system

Single Carrier-Frequency Division Multiple Access (SC-FDMA) is recommended by Third generation partnership project-long term evolution (3GPP-LTE) for uplink transmission in future generation wireless communication systems. As a result of the peak-to average power ratio (PAPR) is one of the major issues for any kind of uplink transmission, Blind selective mapping technique is proposed in this paper as a PAPR reduction schemes. Simulation results show that the PAPR performance for the proposed B-SLM technique is approximately the same as the PAPR performance of the Convectional Selective Mapping C-SLM but, B-SLM technique provides a reduction in bandwidth without a significant degradation in Bit-Error Rate (BER) performance. Also the effect of solid state power amplifier (SSPA) on the performance of SC-FDMA system is investigate.
