Description
Summary:In this letter, a polarization diversity technique applied to massive multiple-input-multiple-output (MIMO) in an industrial environment is proposed. The main idea is to use dual-polarized elements at the fixed array and to adequately choose their polarization for each communication channel between this array and a given user. For the same number of antenna ports, such a configuration allows decreasing, by a factor of 2, the geometrical size of the array and, thus, minimizing the spatial nonstationarity over the array. Performance of this approach is evaluated in terms of the sum-rate capacity assuming either a maximum ratio transmitter or a zero-forcing precoding and is based on channel matrices measured at 3.5 GHz in an industrial hall.
