论文摘要
在这项研究中，我们提出了基于循环chir刺的宽带指数调制（IM）。为了得出所提出的方法，我们首先证明可以通过线性结合傅里叶序列的chir曲线来构建Golay互补对（GCP）。我们表明，源自正弦和线性鸣叫引起的菲涅尔积分和/或贝塞尔功能可以导致GCP。然后，我们利用离散的傅里叶变换 - 传播正交频施加多路复用（DFT-S-OFDM）以获得低复杂性发射器和接收器。我们还讨论了它在达到峰值信封功率比（PMEPR）和光谱效率（SE）之间取舍的概括。通过全面的模拟，我们将提出的方案与DFT-S-OFDM与IM与IM和IM和IM和互补序列（CSS）（RM-Muller（RM）代码的正交频施加多路复用（OFDM）进行了比较。我们的数值结果表明，提出的方法在利用频率时限制了PMEPR。
In this study, we propose a wideband index modulation (IM) based on circularly-shifted chirps. To derive the proposed method, we first prove that a Golay complementary pair (GCP) can be constructed by linearly combining the Fourier series of chirps. We show that Fresnel integrals and/or Bessel functions, arising from sinusoidal and linear chirps, respectively, can lead to GCPs. We then exploit discrete Fourier transform-spread orthogonal frequency division multiplexing (DFT-s-OFDM) to obtain a low-complexity transmitter and receiver. We also discuss its generalization for achieving a trade-off between peak-to-mean envelope power ratio (PMEPR) and spectral efficiency (SE). Through comprehensive simulations, we compare the proposed scheme with DFT-s-OFDM with IM, orthogonal frequency division multiplexing (OFDM) with IM and complementary sequences (CSs) from Reed-Muller (RM) code. Our numerical results show that the proposed method limits the PMEPR while exploiting the frequency.
