Real-Time Subspace Tracking Algorithm Based on Multistage Wiener Filter

摘要

The purpose of this paper is to estimate the interference subspace quickly. The fundamental of Multistage Wiener Filter(MWF) is given. The shortage of the MWF is pointed out and then a new real-time subspace tracking algorithm is propounded. Theoretical analysis and simulation results show that the interference subspace could be tracked quickly by utilized this algorithm.
