The invention relates to a method for selecting modes for a system for MIMO transmission over a multimode optical fibre. Said method includes a step of measuring (110) the transfer matrix of the transmission channel consisting of a set of modes of the optical fibre, a step of converting (120) the transfer matrix into a block diagonal matrix, each block being associated with a subset of modes, a step of determining (130) the gain and/or transmission capacity for each of the mode subsets, and selecting (140) the mode subset corresponding to the greatest gain and/or capacity, the MIMO transmission system therefore using only the subset modes thus selected for transmission over the optical fibre. The invention also relates to a method for selecting cores for a system for MIMO transmission over a multicore optical fibre. |
