摘要 垂直分层空时编码(V-BLAST)将空间复用和空间分集结合起来,能够提高系统的传输速率,因此,提出一种基于V-BLAST的光纤IMMO系统。光纤IMMO技术主要是利用MIMO技术将多模光纤(MMF)的模式色散加以利用,改善MMF的容量。构建光纤信道模型,在接收端,采用最小均方误差算法进行检测,仿真分析基于V-BLAST的光纤IMMO信道容量变化及误码率性能,结果表明采用V-BLAST的光纤IMMO系统能够带来很好的系统容量和误码率性能。 Vertical bell labs layered space-time(V-BLAST) is a technology combining space multiplexing with spatial diversity to improve transmission rate,so proposed a new optical fiber multiple-input multiple-output(MIMO) system,which based on V-BLAST.Multi-input multi-output(MIMO) technology is using the mode dispersion to prompt the MMF capacity.Constructing the MMF channel model,and using MMSE detected the received signal matrix in receiving terminal.The simulation result shows that the capacity is rising with the number of lasers rising,and when the number of receivers is more than that of transmitters,the OMIMO has better capacity and BER.
