BIMA: Blind iterative MIMO algorithm
Tobias Dahl, Nils Christophersen, David Gesbert · IEEE International Conference on Acoustics Speech and Signal Processing · 2002
Identification of the channel matrix is of main concern in wireless MIMO (Multiple Input Multiple Output) systems. Here, we present an SVO-based approach for blind identification of the main independent parallel channels. The right and left singular vectors are estimated directly (no channel matrix estimation is necessary) and continuously updated during normal transmission. The approach is related to the iterative Power Method (8), as well as the time reversal approach ([4]).
