MVDR Spectrum Estimation Algorithm

This is a MATLAB-based implementation of the Minimum Variance Distortionless Response (MVDR) spectrum estimation algorithm, designed for accurate power spectrum analysis. The algorithm employs the principle of minimum variance unbiased estimation to effectively estimate and analyze signal power spectra. The implementation utilizes key MATLAB functions including covariance matrix computation, eigenvalue decomposition, and optimal weight vector calculation through quadratic optimization. The program features adaptive array processing techniques that minimize variance while maintaining distortionless response in the desired direction, providing superior resolution compared to conventional periodogram methods. By employing this implementation, users can obtain more accurate and reliable power spectrum estimation results, significantly enhancing the precision and effectiveness of signal processing and spectral analysis applications. The code includes configurable parameters for array geometry, snapshot numbers, and regularization factors to accommodate various operational scenarios.
