| 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。

| Abstract: | 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. |
