Semi-blind channel estimation on inaccurate noise subspace for MIMO systems

Abstract

An approach to improve the performance of subspace-based channel estimation for multiple-input multiple-output (MIMO) systems is proposed. In a subspace-based channel estimation method, a small number of received blocks cause the residual error which affects the accuracy of the noise subspace because the covariance matrix is estimated from the received… (More)
