查询词典 invariant subspace

Coherent interference can be suppressed by the EMCMVB efficiently. The EMCMVB first gets the modified signal subspace by using the estimated arrival angles of coherent interferers and the eigenstructure of the correlation matrix, and then projects the MCMVB weight vector onto the modified signal subspace.

EMCMVB是利用估计得到的相干干扰方向和阵列信号相关矩阵特征分解来得到修改的信号子空间，再把多约束最小方差波束形成器的权矢量向修改的信号子空间投影来得出新的权矢量。

However, blind channel estimation is a very complex, very fargoing research topic. Because of the author's limit ability and time, only the simple subspace channel estimation method is studied. In the third part of this dissertation, the subspace channel estimation method in MIMO-OFDM systems is investigated.
