N2 - This paper proposes an iterative updating method of an oblique projection matrix. Recently, oblique projection have received much attention in signal processing. However, in derivation process of an oblique projection matrix, computational complexity of the cube of subspace rank is required because of inverse matrix calculation. Moreover, we must know the bases of desired signal subspace and interference signal subspace as preamble information. Therefore, we propose an iterative updating method of the oblique projection matrix only from the bases of desired subspace to avoid the inverse matrix calculation. Simulation result shows effectiveness of the proposed method.
