摘要 本文首先介绍了LTE系统中OFDMA、SC-FDMA多址接入技术的原理以及信号实现过程,然后对两种多址接入方式进行了分析比较,验证OFDMA接入技术的PAPR(峰均比)高于SC-FDMA,并给出了仿真结果,最后,提出研究降低OFDMA系统PAPR算法的必要性。 This paper first introduced the principle and signal realization of OFDMA and SC-FDMA in LTE system, second, by analysis of the differences between OFDMA and SC-FDMA, the result that PAPR of OFDMA was higher than SC-FDMA’s was verified, then computer simulation of PAPR was given. At last, this paper proposed the necessity of algorithm research of reducing PAPR of OFDMA.
