摘要
在室内可见光通信MIMO通信系统中,信号的多径传输会产生严重的码间干扰,影响系统的传输性能.为了减小系统的码间干扰,通过室内可见光MIMO通信系统的信道特性分析,采用最小二乘法(LMS)、递归最小二乘(RLS)算法对信道进行补偿.仿真结果显示,采用均衡技术可以有效降低系统的误码率,相比LMS算法,系统采用RLS算法的误码率更低,收敛速度更快.
：In the indoor visible light communication （MIMO） communication system, multipath transmission of signals causes serious inter symbol interference, which affects the transmission performance of the system. In order to reduce the inter symbol interference, the channel characteristics of indoor visible light MIMO communication system are analyzed by using least square method （LMS） and recursive least squares （RLS） algorithm. The simulation results show that the algorithm can reduce the bit error rate of the system effectively, and compared with the LMS algorithm, the RLS algorithm has lower bit error rate and faster convergence rate.
