| 摘 要： | 简要介绍了固定宽带无线接入标准IEEE 802.16以及一种用于信道均衡的自适应算法——指数加权RLS，对判决导引信道均衡技术的原理进行了具体描述。最后分别就两种自适应的均衡算法（LMS、RLS），结合一种具体IEEE 802.16单载波调制系统推荐测试信道进行了仿真，得出RLS算法优于LMS的结论。

| Abstract: | The fixed bvoadband wireless access(BWA) standard IEEE 802.16 and a DFE equalization algorithm : exponential weighting recursive least squares(RLS)are introduced,the principle of Training/Decision-Directed channel equalization technique is described.Finally,according to a special(IEEE 802.16) test channel model,the performance of two equalization algorithms LMS and RLS is simulated,and it is found that the RLS algorithm is superior to LMS algorithm. |

| Keywords: | BWA system single-carrier modulation channel equalization adaptive equalization |
