基于MUSIC算法的混合信号频率估计方法研究.pdf

of mixed signal with noise, mainly involves the principle of music algorithm, algorithm realization

steps, advantages and disadvantages, MATLAB software implementation and simulation algorithm,

generating spectral density image, analyzing the calculation amount of this algorithm, the principle

error of the algorithm and data result error, etc. In this paper, the correlation matrix R is estimated

analysis show that music algorithm can achieve high-precision mixed signal although it has large

calculation amount Frequency estimation.
