Blind Identification of MIMO-OFDM Channels Driven by Colored Source with Unknown Statistics
Xi Chen, A.R. Leyman · 2007
We present a closed-form solution for blind multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM ) channel estimation driven by colored sources with unknown statistics. The uniqueness of the solution is proved by exploiting the inherent structural relationship of the source and received signal autocorrelation matrices. Computer experiments results are presented to illustrate the performance of the proposed algorithm.
