【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.更多还原

【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.更多还原
