摘　　要：在无线衰落的通信信道中,空时编码的多输入多输出的(MIMO)系统具有很好的性能,但是多址干扰也很严重.提出一种自适应线性约束的二阶最小均方(LC-SOLMS)空时抗干扰算法,来抑制多址干扰和噪声.模拟结果证明:该算法具有较好的干扰抑制能力和快速的收敛性能.In wireless communication channels, multiple-input multiple-output （MIMO） systems with space-time block codes（STBC） are usually used to eliminate multipath fading, wherein multiple access interference is very serious. An adaptive linearly constrained second-order least mean-square （LC-SOLMS） algorithm was proposed to reduce the interference and noise. The simulation results illustrate that the proposed algorithm has great interference cancellation capability and faster convergence performance.
