摘　　要：利用导频插入对瑞利衰落信道进行估计,运用正交空时分组编码和最大似然解码,仿真结果显示:插入导频后的误比特率曲线比没有插入导频的误比特率曲线性能有所提高,随着导频数目的增加,系统的误比特率有所下降。估算方法有效提高了信道估算性能,且运算量增加不大。Using inserting pilots into frames, Orthogonal Space-Time Block Coding and maximum likelihood decoding, the estimation of Rayleigh fading channels is proposed, the simulation result shows that using inserting pilots provides remarkable performance, if the number of pilots is increased, BER is reduced. The estimation demonstrates that the increase of channel estimation performance can be achieved with little added complexity.
