摘要
随着世界经济的迅速发展和陆地可利用资源的快速消耗,人们越来越关注蕴含丰富资源的海洋区域,而对海洋资源的开发需要水下无线通信技术的支持。文章重点研究采用多入多出技术的水下可见光通信系统,充分利用了空间分集的优势。通过实验评估采用正交频分复用的可见光通信系统的误码率,包括单进多出、多进单出以及多进多出。实验结果显示,我们提出的系统配置通过改善误码率,确实能大大提升系统性能。
With the rapid development of the world economy and the rapid consumption of available resources on land, people are paying more attention to the marine areas with abundant resources, and the development of marine resources need the support of underwater wireless communication technology. This paper investigates the performance of underwater visible light communications(UVLC) systems employing multiple transmitters and/or multiple receivers to exploit the advantage of spatial diversity.Experimental results are further provided to evaluate the error performance of single input multiple outputs(SIMO), multiple inputs single output(MISO) and multiple inputs multiple outputs(MIMO) UVLC systems when orthogonal frequency division multiplexing(OFDM) modulation is utilized. Our results reveal that the proposed system configuration can indeed offer significant system performance enhancements in terms of the attainable bit error rate.
