| 摘 要： | 基于子空间的MIMO-OFDM盲信道估计算法传输效率较高,但是算法计算量较大且接收端需要较多的信号才能进行精确估计.本文将基于噪声子空间的跟踪算法应用到MIMO-OFDM系统进行信道估计,并且对接收信号进行重构,达到了降低算法复杂度的目的,并减少了对接收信号数量的需要.

A Subspace-based MIMO-OFDM Blind Channel Estimation for MIMO-OFDM System |

| Abstract: | The blind channel estimation of MIMO-OFDM based on subspace has high efficiency of transport,but the algorithm needs a large amount of calculation.Besides,we need more signals to estimate exactly.MIMO-OFDM blind channel estimation based on noise subspace tracking is applied to reduce the complexity of the algorithm.Furthermore,the received signals are reconstructed to reduce the need for the received signals. |
