摘要
文中介绍改进过零点检测算法。利用过零点计数和多数值拟合的办法计算调制符号的翻转点位置。实验结果表明本文方法适用于大多普勒频偏信号。
A novel modified zero crossing detection method is introduced. With zero-crossing counting and data fitting, the exact time of chip flip is calculated. Experiment results indicate that this algorithm performs well under a significant Doppler frequency shift.
