副载波STBC-MIMO紫外通信系统性能分析
Performance Analysis of Subcarrier STBC-MIMO in Ultraviolet Communication System
紫外光通信因其高保密、抗干扰、非直视等优势在战地通信和城市管理领域具有广泛的应用前景。为解决紫外光通信在实际应用中面临的低速率、高误码的问题，我们基于副载波调制和空时编码（STBC）技术，提出了一种紫外MIMO分集通信方案。在此基础上设计了2×2紫外MIMO实验平台。通过仿真和实验验证了紫外通信中，副载波STBC-MIMO能有效地提升传输速率，降低系统误码率。
Ultraviolet communications have broad application prospects in the field of battlefield communications and city management for its high security, anti-interference and non-line of sight (NLOS). To solve the problem of low transmit rate and high bit error rate in ultraviolet communication, we proposeasubcarrier modulation and space-time block coding (STBC) basedcommunicationscheme for ultravioletmultiple-input-multiple-output (MIMO) diversity. Then we design a 2×2 ultraviolet MIMO system. Thesimulation and the experimentprove that subcarrier STBC-MIMO is an efficient approach to increase transmit rate and reduce system bit error rate.
