Abstract

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.
