Abstract
In this paper, we propose a subspace tracking method for blind signature waveform estimation. In practice, the signature waveform can not change suddenly. So, we can take use of the past information of the signal subspace to update the signal subspace gradually for blind signature waveform estimation. After the algorithm proposed in this paper, the computation complexity is reduced substantially.
