Adaptive Generalized Eigenvector Tracking Algorithm for Signal Enhancement
The generalized eigen-decomposition plays important roles in modern adaptive signal processing applications.In this paper
a novel unconstrained cost function for the generalized eigen-decomposition is presented and the properties of the cost function are analyzed.By applying recursive least-squares technique to minimize the cost function
an adaptive algorithm is proposed for finding the most dominant generalized eigenvector.The algorithm is also applied for the beamforming of the smart antenna in CDMA systems.The simulation results show the proposed algorithm has fast convergence and dynamic tracking capability.
