Abstract

A FOCUSS-based subspace method is proposed for blind channel identification, which is robust to channel order overestimation. Based on the sparsity of the desirable channel estimation to order overestimation, a weighted constraint is used to search the sparse solution, combining with the lp norm FOCUSS algorithm, then augmented Lagrange function is applied to improve the robustness of the FOCUSS algorithm. The simulation results show proposed algorithm owns better robustness to order overestimation than existing algorithms.
