This paper demonstrates how you can use MATLAB® and Simulink® features and toolboxes to: design and synthesize complex antenna elements and MIMO phased arrays and subarrays; partition hybrid beamforming systems intelligently across RF and digital domains; validate spatial signal processing algorithm[r]

Linear Minimum Mean-Square-Error Transceiver Design for Amplify-and-Forward Multiple Antenna Relaying Systems

A compact 6-port MIMO antenna consisting of equilateral triangle elements have demonstrated in order to miniaturize the size and reduce the mutual coupling of antenna elements due to its geometrical shape. The antenna is designed on FR4 material and simulated results by HFSS software are provided.

It is important to note that the geometrical model just described is general, and allows any orientation of the two URAs used in the communication link. Another interesting observation is that the geometrical model incorporates the case of ULAs, for example, by employing[r]
