In this paper, we demonstrate a Toeplitz concatenated matrix aided independent component analysis (TCM-ICA) equalizer that can skillfully compensate for the inter-channel interference (ICI) of super-Nyquist multiband carrierless amplitude and phase modulation (m-CAP) system. In the point-to-point super-Nyquist m-CAP visible light communication (VLC) scenario, we experimentally demonstrated a system-level average spectral efficiency (SE) enhancement of 0.50 b/s/Hz in comparison to the conventional scheme. In the multiple-input single-output (MISO) super-Nyquist 5-CAP scenario, the subcarrier-level Q factor enhancements of 4.4 dB, 5.2 dB, and 6.5 dB are achieved in comparison with the least-mean-square (LMS) post-equalizer for the 2^nd, 3^rd and 4^th subcarrier, respectively. As far as we know, the TCM-ICA equalizer is the most effective ICI compensation scheme to enhance SE in the super-Nyquist m-CAP systems.

超奈奎斯特多频带CAP VLC系统的Toeplitz级联矩阵辅助ICA算法

在本文中，我们演示了Toeplitz级联矩阵辅助独立分量分析（TCM-ICA）均衡器，该均衡器可以熟练地补偿超奈奎斯特多频带无载波幅度和相位调制（m -CAP）系统的信道间干扰（ICI）。在点对点超级奈奎斯特m -CAP可见光通信（VLC）方案中，我们实验证明了与传统方案相比，系统级平均频谱效率（SE）增强了0.50 b / s / Hz。在多输入单输出（MISO）超级奈奎斯特5-CAP方案中，与最小均方（LMS）相比，子载波级Q因子增强了4.4 dB，5.2 dB和6.5 dB。^第二，^第三后均衡器和^第4^个副载波。据我们所知，TCM-ICA均衡器是增强超级奈奎斯特m -CAP系统SE的最有效的ICI补偿方案。
