Abstract:
1. A wireless communication node adapted to be connected to or comprising an antenna part with a plurality of antenna elements and an antenna port for each antenna element, the wireless communication node comprising: a plurality of feeder ports adapted to be connected to the antenna ports, each antenna port being associated with a unique antenna port identification, and each feeder port being associated with a unique feeder port identification; a signal handling and estimating unit adapted to collect signals from a mobile station and to, for signals received over antenna ports of a first, same, polarization, generate a plurality of channel estimates; a connection combination information holding unit adapted to hold information about all possible connections between feeder ports and antenna ports; and a processing unit comprising or communicating with: a channel modelling unit adapted to provide a channel model for the signals received over the co-polarized antenna elements; a channel model fitting unit adapted to compare the channel model with the channel estimates for a plurality of permutations obtained by the connection combination information; and an order identifying unit adapted to identify the feeder port connection order corresponding to the permutation order giving the best fit between channel model and channel estimates as the current feeder port connection order.
