22966 针对室内可见光通信调制技术和多用户接入问题，该文基于直流偏置和极性编码信号单极化思想提出两种系统复杂度低、频带利用率高的可见光多维无载波幅度相位(DCO-MCAP,  U-MCAP)调制方案。 Considering the modulation technique and multiple-access topology for indoor Visible Light Communication (VLC), two Multi-dimensional Carrierless Amplitude and Phase (Multi-CAP) modulation schemes are proposed in this paper, namely, DC biased Optical Multi-CAP (DCO-MCAP) and Unipolar optical Multi-CAP (U-MCAP).
22967 首先利用最大最小优化算法构建无频谱泄漏的频域目标方程，采用完全重建(PR)条件作为非线性约束方程，求取时域正交的多维CAP 滤波器组，然后分别采用“添加直流偏置”和“零值位置极性编码”实现信号单极性，以满足可见光通信“强度调制/直接检测”的要求。 The design object is modeled as a mini-max optimization problem with a non-constraint condition named Perfect Reconstruction (PR), which can be solved by the quadratic programming algorithm. Only real and unipolar signals can be intensity modulated, therefore several modifications are performed in CAP VLC systems accordingly. A DC bias added to the signal and a pair of new samples including a zero padding to mark signal polarity are adopted to obtain unipolar signal respectively.
22968 基于朗伯辐射模型，可见光背景噪声建模为加性高斯白噪声(AWGN)，推导了 DCO- CAP/MCAP, U-CAP/MCAP 4 种调制方案的误符号率理论解，仿真验证了其准确性。 According to Lambertian reflection model and considering light of sight link corrupted by Additive White Gaussian Noise (AWGN), the theoretical Symbol Error Rate (SER) of DCO-CAP/MCAP and U-CAP/MCAP are derived and corroborated by Monte Carlo simulations.
22969 在 5 m´5 m´3 m 的室内场景下，仿真对比分析了 2 维、3 维、4 维可见光 CAP 调制系统的频带利用率、误码率等性能。 Meanwhile, the performance of three kinds of dimensional (2D, 3D, 4D) optical CAP systems are analyzed and compared in the room in size of 5 m´5 m´3 m.
22970 结果表明，相同星座尺寸时，多维 CAP 调制的误码性能明显优于传统 2 维；相同频带利用率时，3 种维度系统误码性能相近，可见光多维 CAP 调制为多用户接入提供可能性。 The numerical results show that the error performance of optical Multi-CAP is superior to that of traditional two dimensional optical CAP with the same constellation, and the multi-CAP (3D or 4D) scheme can not only achieve approximate SER performance with respect to the same bandwidth efficiency, but also enable multiple access in VLC system.
22971 此外，讨论了信道参数对可见光 CAP 系统的影响，发射机辐射角与收发信机之间距离都与信噪比损失呈现出正相关性。 In addition, the effects of channel parameters on the system performance are evaluated which shows that the loss of SNR obviously presents positive relation with the increase of the radiation angle or the distance between the transmitter and the receiver.
