Abstract
Aiming at the problem of signal transmission channels phase estimation,a kind of algorithm for channels phase utilizing Chebyshev orthogonal polynomial approximation function is proposed. The algorithm calculates the input value of arctan function through the method of quadrant distinguish and interzone partition. Then channels phase is calculated utilize Chebyshev orthogonal polynomial approximation function. At last,calculation is predigested by iterative algorithm. The algorithm has the characteristic of simple,fast estimation speed and high precision.关键词
