摘要
V&V算法是一种经典的开环载波相位估计算法,在突发数据通信中应用广泛。针对该算法存在相位模糊抖动问题,提出了一种改进型的V&V算法。仿真结果表明该算法不仅可以消除原算法中遇到的相位模糊抖动问题,同时还可以在相同估计精度的条件下将时延缩短一半,而且算法实现比较简单。该算法适用于要求载波相位估计时延很短的突发通信。
V＆V algorithm is a kind of classical open loop carrier phase recovery algorithm which is widely used in burst digital communication： A modified V＆V algorithm is proposed to solve the equivocation problem meeted in the V＆V algo-rithm. Simulation results illustrate that it can not only solve the equivocation problem but also shorten the converging time for a hall. And it is easy to implement. This algorithm is very suitable for application to burst digital transmission.
