%X A QR factorization based blind estimation algorithm has good performance. By combining the QR factorization based algorithm with the special structure of Orthogonal space-time block code, a new blind estimation algorithm in OSTBC was proposed. Compared with the traditional blind estimation methods, the proposed algorithm has much lower computational costs. And the Monte-Carlo simulations show that when the SNR is low, the proposed algorithm outperforms the subspace method based blind estimation algorithm.
