At least one master unit communicates with the MIMO base station. At least one remote unit communicates with the master unit. At least one antenna is coupled with the remote unit for receiving signals from the remote unit. A coupler element is configured for introducing a phase shift in a portion of at least the first MIMO signal and for combining the phase shifted first MIMO signal portion with a portion of the second MIMO signal and presenting the combined first and second MIMO signal portions at an output port of the coupler element. An antenna is configured for receiving the combined MIMO signal portions for transmission."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distributed antenna system for MIMO signals","description":"A distributed antenna system includes a multiple-input and multiple-output (MIMO) base station configured to output at least a first signal and a second signal.
