A Low Complexity Antenna Selection Algorithm for MIMO System

The performance of Multiple-input multiple-output (MIMO) system can be improved by employing a large number of antennas than actually used and selecting the optimal subset based on the channel state information at receiver. Antenna selection is used for increasing the channel capacity of MIMO systems and reducing the systems complexity and cost of RF chains. In this paper we propose an effectiv...

Evaluating the deformation monitoring capability of a ground based SAR system with MIMO antenna

By increasing the applicability of ground-based SAR (GBSAR) systems in geoscience and remote sensing, the development and evaluation of new systems have gained attention. GBSAR systems can be utilized for monitoring areas that are hard to or cannot be seen by the airborne or spaceborne systems. Furthermore, they have better spatial and temporal resolutions and are cost-effective and easy to imp...

Low-complexity multiuser MIMO downlink system based on a small-sized CQI quantizer

It is known that the conventional semi-orthogonal user selection based on a greedy algorithm cannot provide a globally optimal solution due to its semi-orthogonal property. To find a more optimal user set and prevent the waste of the feedback resource at the base station, we present a multiuser multiple-input multiple-output system using a random beamforming (RBF) scheme, in which one unitary m...
