摘要

本文提出了一种用于盲信号波形估计的子空间跟踪方法。在实际应用中，信号波形不会发生突然变化。因此，我们可以利用信号子空间的过去信息逐步更新信号子空间进行盲签名波形估计。本文提出的算法大大降低了计算复杂度。

Fast blind signature waveform tracking under imperfect carrier recovery in DS-CDMA systems

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.
