摘要
在介绍一种新型的卫星多址方式—PCMA(成对载波多址)技术的基础上,利用Fisher矩阵得到信道参数估计的克拉美罗限,并结合ML(最大似然准则)和锁相环技术提出了一种无需单独发送训练序列的新分离算法。仿真结果证实了该算法的有效性和可行性。
Based on the introduction of a new multiple access mode—Paired Carrier Multiple Access （PCMA） in satellite, the Cramer-Rao Lower Bound（CRLB） of channel parameters estimation were deduced by Fisher matrix . Jointed the maximum-likelihood （ML） principle and phase locked loop（PLL） , a new separation algorithm without separately sending training sequences was proposed. The simulations testify the validity and the feasibility of the algorithm.
