- 本文利用软输入软输出信道译码器输出对数似然比随相位偏差变化的规律得到低信噪比MPSK信号的 相位偏差代价函数,并提出一种求解该代价函数的迭代相位搜索方法,以相对较小的运算量实现较高精度的相 位估计。仿真表明,该算法在低信噪比下具有稳定的性能,并且能够克服大多相位估计算法都存在的相位模糊 问题。-In this paper, the soft input soft output channel decoder output log-likelihood ratio with the v

- 一种未知信源数的高分辨DOA 估计算法:众多性能优良的超分辨波达方向(DOA)估计算法通常需要预先判定信源数目,然而,现有的信源数估计 算法在有限采样快拍条件下,估计性能随着信噪比的降低而下降,错误概率也相应增加,最终导致DOA 估计失败。 该文提出一种超分辨的DOA 估计算法,此算法不需要预判信源个数和进行特征值分解,同时在时变环境中,针对 快拍数较少的情况下,依然保持较高的角度分辨能力,可以被认为是综合了Capon 法和MUSIC 法的优点。-Algorithm on High
