【摘要】 交织子载波索引调制OFDM系统(ISIM-OFDM)是一种改进的SIM-OFDM系统,其主要思想是通过交织使得同一子块的子载波信道衰弱不相关,增大了最小欧氏距离,从而提升系统性能。在这篇文章中,ISIM-OFDM的系统性能被分析并得到一个闭合表达式,通过蒙特卡洛仿真验证了分析得出的ISIM-OFDM的BER性能的正确性。更多还原

【Abstract】 Interleaved Subcarrier index modulation orthogonal frequency division multiplexing(SIM-OFDM)is a revised technique which modulates part of the information bits by the indices of OFDM subcarriers,so called SIM-OFDM systems.The main idea is through the interleaving,the channel efficient from the same subblocks turned to be uncorrelated,promote the performance by enlarging the Euclidean distances among the modulated symbols.We derived the performance of ISM-OFDM and get a closed expression,and simulation results show that the proposed interleaved SIM-OFDM(ISIM-OFDM) can get the same BER performance.更多还原
