Abstract: This paper investigates the convergence-enhanced subspace channel estimation technique for multiple-input–multiple-output (MIMO)-orthogonal frequency division multiplexing (OFDM) systems with or without virtual carriers (VCs). Since the perturbations of the correlation matrix and the noise subspace are…
