1 College of Communication Engineering, Jilin University, Changchun 130012, China ([email protected]) 2 School of Electronics and Information Engineering, Shenyang Aerospace University, Shenyang 110136, China Abstract A subspace based speech enhancement algorithm with low complexity is proposed by using our improved subspace iteration method. Due to the use of the iteration, the proposed algorithm can greatly reduce its number of calculation or its complexity with satisfied performance in speech enhancement in the case of both white and color noise, which proves that it is more suitable for real time implementation. Simulation results show that the proposed algorithm can achieves better speech enhancement compared with classical subspace based algorithm in low input SNR.
