Spatial multiplexing and channel statistics-based RF pre-processing for antenna selection

For a multiple input multiple output system, antenna selection reduces complexity at the expense of performance. In this paper, we propose two novel RF pre-processing architectures that significantly improve the performance of antenna selection, while marginally increasing the complexity. These architectures introduce an RF pre-processing matrix, M, that multiplies the vector of incoming signals p

2014 is by the Polish government declared as the year of Jan Karski. Fourteen years after his passing, Karski has become an official Polish representative when discussing world politics.
