基于多包络方法的3D双模OFDM-IM调制及其性能分析
3D dual-mode OFDM-IM modulation with multi-envelope approach and performance analysis
摘要
Abstract
To address the issues of high bit error rate and limited anti-interference capability in current high-dimensional OFDM index modulation systems,a dual-mode orthogonal frequency division multiplexing index modulation scheme based on multi-envelope three-dimensional constellation modulation(3D-DM-OFDM-IM)was proposed.The scheme employed a method of inscribing regular polyhedrons within multiple spherical envelopes to design a 3D constellation diagram.Compared to existing 3D constellation mapping schemes,the minimum Euclidean distance between constella-tion points has improved.Simulation results show that under the condition of ensuring the same spectral efficiency,the proposed scheme achieves better bit error rate performance and lower peak-to-average power ratio compared to the exist-ing 3D dual-mode OFDM-IM modulation scheme,regardless of low-order modulation or high-order modulation.关键词
