| 摘 要： | 当信道被过估计时，用标准子空间法可得到多个线性独立的信道估计，而真正的信道向量处在这些线性独立解所张成的范空间内．通过引入约束条件，信道向量可以被唯一确定,在快速收敛的同时，对信道过估计具有很高的鲁棒性．

| Abstract: | When channel is over-estimated, multiple linear independent channel estimation are obtained using standard subspace method. The true channel vector lies in the range space spanned by these independent solutions. By a constrained condition, the true channel solution can be decided uniquely. The method converges fast and is robust to channel over-estimation. |
