Explore MATLAB source code curated for "信号频率估计" with clean implementations, documentation, and examples.
Custom MATLAB code implementing the ESPRIT algorithm for accurate signal frequency estimation, featuring optimized matrix operations and eigenvalue decomposition for enhanced performance.
Three complex sinusoidal signals with SNR values of SNR1=30dB, SNR2=30dB, and SNR3=27dB were analyzed using an MVDR method based on singular value decomposition (SVD). The simulation employed 1000 signal samples and a 4-tap FIR filter to estimate the power spectral density function. The implementation involves covariance matrix construction, eigenvalue decomposition, and adaptive weight calculation for spectral estimation.
