Hai Ping Zhu, Wensen Shi, Peng Cai · 2011
The purpose of this paper is to estimate the interference subspace quickly. We show that the solution of the proposed constrained optimization problem results the signal subspace. Then a novel subspace tracking algorithm is propounded. Theoretical analysis and simulation results show that the interference subspace could be tracked quickly by utilized this algorithm.
