An inverse iterative subspace method for SIMO blind identification is proposed based on the cross relations over the time dispersive channel. A first order perturbation analysis is conducted on the proposed estimator. In order to intensify the stability of the proposed estimator, an iterative inverse CR matrix is also presented by using the perturbation theory and Taylors expansion up to the first order. Theoretical analysis and experimental results demonstrate that the proposed estimator has a better performance over the existing blindly adaptive algorithms, the method of iterative inverse CR matrix is not only simple but also valid, and there exits a high consistency between the perturbation analysis and the experimental results.
