Abstract :
A recent work by Tong et al. (see IEEE Trans. Information Theory, vol.40, no.2, p.340, 1994) provides a novel second-order statistics based method for blind channel identification. In this paper, we present a first-order perturbation analysis of the large-symbol-size performance of this method. An explicit expression for the mean square error (MSE) of the channel estimate is derived. Both the theoretical and simulation results are used to analyze the statistical performance of this method. A number of new insights are revealed
