摘要
本文导出了最大熵谱计算的一种新的快速递推算法,将原计算谱值中三角函数的复数运算化为一般自然数的四则运算,使计算效率提高到4倍多。
This paper derives a new fast recurrent algorithm (RA) for ME spectral estimation, which turns trigonometry function operation in complex domain into adding and multipling operation in real domain. By this way, the computational efficiency is further raised.
