提出了一种计算复数相角的新算法。该算法利用对三角函数的线性拟合及三角函数的近似式递归迭代,显著地提高了算法的效率及运算结果的精度。与传统算法相比,该算法收敛速度快,运算精度高,可以满足实时处理控制的要求。在普通PC机及高速DSP芯片上的试验也充分验证了这一点。

[Abstract]
An new algorithm for calculating the phase angle of complex number is proposed. Compared with traditional algorithms, the new one improves the calculation speed greatly. The results of tests on PC and high-performance DSPs show that it also can achieve high-accuracy. So it is suitable for real-time processing,
