摘要

摘要: 针对大量出现的未知猝发类幅相调制信号，包括PSK, APSK, QAM等，该文提出一种通用的前向载波相位恢复方法。该方法基于星座对称性，从星座点的相位信息出发，构造折叠相位(WP)统计量，实现了此类信号无区分调制类型，无需训练序列的载波相位盲估计。仿真表明，此方法相比现有算法，相同数据量，相同信噪比下优势明显，灵活性，鲁棒性均优于现有算法，适合非合作接收条件下猝发信号处理工程实践。

Abstract: For the emergence of massive burst amplitude and phase-modulated signals with uncertain modulation type including PSK, APSK, QAM and so on, a universal algorithm is proposed to accomplish the forward carrier phase recovery. Based on the symmetry of constellation, a statistic of wrapped phase is established from the phase information of the constellation points. As a result, the carrier phase blind estimation for unknown burst signals is accomplished regardless of the modulation type and training sequence. Simulations indicate that compared with the current algorithms, the proposed method has better anti-noise ability, flexibility, robustness, making it a good choice for engineering practice of burst signals under non-cooperative condition.
