摘要

光无线通信(OWC)在许多技术应用中都优于无线电无线通信。为了研究光多输入多输出(OMIMO)信道的特性，本文首先对光无线信道进行仿真，分析色散多径对信道的影响。我们用光线追踪法计算脉冲响应和通道的频率响应，并将反射限制在秒内。然后，我们首先研究了在漫射衰落信道中使用Alamouti空时分组码(STBC)的OMIMO DCO-OFDM，分析了系统的误码率(BER)。对信道和通信系统的仿真结果进行了具体的计算和评价。

Optical MIMO DCO-OFDM wireless communication systems using STBC in diffuse fading channels

Optical Wireless Communication (OWC) is superior to radio wireless communication in several technical applications. In order to study the characteristics of Optical Multiple Input Multiple Output (OMIMO) channels, first, this paper presents the simulation of the optical wireless channel to analyze effects of dispersion multipath. We use ray tracing method to calculate the impulse response as well as the frequency response of the channel limit the reflections within seconds. Afterwards, we firstly investigate the OMIMO DCO-OFDM using Space Time Block Code (STBC) of Alamouti in diffuse fading channels to analyze the bit error rate (BER) of the system. The simulation results of the channel, as well as the communication system, are calculated and evaluated specifically.
