Coordinated MIMO with single-fed load-controlled parasitic antenna arrays

In this work, we present a method that enables the application of robust, low-complexity, arbitrary channel-aware precoding at single-fed load-controlled parasitic antenna arrays. Moreover, we describe the extension of this technique to multi-cell setups. Finally, we evaluate the sum-rate throughput performance of several multi-cell precoding schemes through numerical simulations based on realistic radiation patterns generated by antenna design software as well as on a scattering environment model. The results of the simulations confirm the expected performance gains over conventional single-fed configurations.
