An improved fast ESPRIT frequency estimation algorithm is present for reducing the computational load existing in frequency estimation of subspace rotational in variance technology (ESPRIT) algorithm. The improved algorithm does not need eigen-decomposition of auto-covariance matrix, using the sampling signal delay data to construct two sub-arrays with the same array shape, through generalized eigen-decomposition...
