Recursive spatial multiplexing (RSM), a closed loop multiple-input multiple-output (MIMO) structure for achieving the capacity offered by MIMO channels with a low-complexity detector, is investigated in measured indoor MIMO transmission channels limited by different types of interference. It is seen that RSM can deal effectively with interferences following either a Gaussian mixture or Middleton distribution. In cases of interferences which are symmetric alpha stable distributed, however, RSM suffers from a performance degradation. Performance improvements resulting from the use of a convolutional coding at the single-input single-output (SISO) encoder of the RSM architecture are investigated for the different interference distributions.
