摘要 提出了一种改进的向量模式下的CORDIC算法——MV-CORDIC算法,可以用来实现通信系统中频偏估计幅角的计算。仿真结果表明,该算法相比传统的CORDIC算法,可以大幅度减少CORDIC算法的迭代次数。算法输出幅角的误差小,可以利用其实现频偏估计中幅角的计算。 This paper proposes, which is MV-CORIDC a modifies vector mode CORDIC algorithm. It is used for computing the angle of frequency offset estimation in communication systems. Simulation results show that the MV-CORDIC algorithm efficiently reduces the number of iterations compared with original CORDIC algorithm.
