ABSTRACT:
A matrix{circumflex over (V)}of eigenvectors is derived using an iterative procedure. For the procedure, an eigenmode matrixViis first initialized, e.g., to an identity matrix. The eigenmode matrixViis then updated based on a channel response matrixĤfor a MIMO channel to obtain an updated eigenmode matrixVi+1. The eigenmode matrix may be updated for a fixed or variable number of iterations. The columns of the updated eigenmode matrix may be orthogonalized periodically to improve performance and ensure stability of the iterative procedure. In one embodiment, after completion of all iterations, the updated eigenmode matrix for the last iteration is provided as the matrix{circumflex over (V)}.
