Performance analysis of a second order statistics based solution for the MIMO channel identification problem
João Xavier, Victor A. N. Barroso · 2002
The CFC/sub 2/ algorithm is a recently introduced analytical solution for the blind MIMO channel identification problem, provided a certain spectral diversity holds for the stochastic inputs of the MIMO system. Here, we develop a theoretical study to derive the asymptotic performance of the CFC/sub 2/ algorithm, in terms of mean-square error. Asymptotic normality of the MIMO channel estimate is proved, and the asymptotic error covariance matrix derived. Computer simulation results are included to validate the theoretical expressions.
