摘要翻译：
一种可见光通信(VLC)系统可以采用多色发光二极管(LED)阵列来支持多个用户。本文提出了一种多层编码和约束部分群译码(CPGD)方法，以解决强彩色干扰，提高系统吞吐量。在建立信道模型后，通过贪婪算法解决最大最小公平性问题，分配用户信息速率，得到所有接收数据层的解码顺序。在截断高斯输入分布下导出了一个可实现的速率。为了降低译码复杂度，在接收平面上为所有感兴趣的位置构造一个关于译码顺序和码率分配的映射，并通过基于分类的算法减小其大小。同时，利用了LED阵列的对称几何特性。最后，提出了发射机-用户关联问题，并用遗传算法进行了求解。观察到，由于减小的干扰电平，当接收机与相应的LED阵列稍微不对准时，系统吞吐量增加，但随后由于减弱的链路增益，系统吞吐量减小。

英文摘要：
  A visible light communication (VLC) system can adopt multi-color light emitting diode (LED) arrays to support multiple users. In this paper, a multi-layer coding and constrained partial group decoding (CPGD) method is proposed to tackle strong color interference and increase the system throughput. After channel model formulation, user information rates are allocated and decoding order for all the received data layers is obtained by solving a max-min fairness problem using a greedy algorithm. An achievable rate is derived under the truncated Gaussian input distribution. To reduce the decoding complexity, a map on the decoding order and rate allocation is constructed for all positions of interest on the receiver plane and its size is reduced by a classification-based algorithm. Meanwhile, the symmetrical geometry of LED arrays is exploited. Finally, the transmitter-user association problem is formulated and solved by a genetic algorithm. It is observed that the system throughput increases as the receivers are slightly misaligned with corresponding LED arrays due to the reduced interference level, but decreases afterwards due to the weakened link gain.
