Abstract
The invention relates to a mode selection method for a system for MIMO transmission on an optical fiber of multimode type. It comprises a step of measuring the transfer matrix of the transmission channel made up of a set of modes of the optical fiber (), a step of transforming () the transfer matrix into a block diagonal matrix, each block being associated with a mode subset, a step of determining () the gain and/or the transmission capacity for each of the mode subsets, and a selection () of the mode subset corresponding to the highest gain and/or capacity, the MIMO transmission system then using only the modes of the subset thus selected to transmit on the optical fiber. The invention relates also to a core selection method for a system for MIMO transmission on optical fiber of multicore type.
