A novel technique for the blind estimation of a channel matrix

In this paper, a novel technique is presented for blindly estimating the channel matrix in an M-sensor K-source system. A special estimated higher-order cumulant matrix of the received data is first constructed. The channel matrix is then estimated by the eigendecomposition of the cumulant matrix. This method does not need any prior information of the signal. Computer simulation results are presented showing that the proposed algorithm is very promising.
