| 摘 要： | 信道估计技术保证了信号传输的可靠性。基于导频的LS信道估计算法，通过导频子信道的响应得到整个信道的响应，能够很好地跟踪信道的变化，在复杂度不高的情况下取得较好的误差性能，具有很好的实用性。仿真结果表明采用LS信道估计后有效的降低了系统的误码率。

| Abstract: | Channel estimation strengthen the reliability of signal transimission. Least-Square channel estimation based on pilot can get complete channel response via pilot subchannel,and follow channel changes well to get better error performance if it is not very complicated, It is with higher practicality. The simulation results show that the LS channel estimation effective decrease the bit error rate of the system. |
