Multi-carrier modulation scheme based on prolate spheroidal wave functions with generalized index modulation

Abstract: BER) 下,能够将检测复杂度由经典 GIM 信号索引 检测方法的 O(mM gn) 降低为 O(gn)。理论与仿真结果表明,所提方法具有更高的系统频带利用率, 如当 BER 为 10 −5 时,相对于基于信号优化分组的 PSWFs 多载波调制,所提方法 SE 提升约 14.5%, 所需信噪比降低约 2.73dB;相对于经典 GIM,SE 提升约 2.9%,所需信噪比降低约 1.92dB。
