Patent ID: 8396368

Claim:
A system comprising: a multiple-input and multiple-output (MIMO) base station configured to output a first branch of a MIMO signal and a second branch of the MIMO signal, the branches of the MIMO signal being in the same frequency channel and one of the branches including signaling parameters; a hybrid coupler coupled to the MIMO base station, the coupler configured to receive the first branch of the MIMO signal and the second branch of the MIMO signal from the MIMO base station on respective first and second input ports and provide output signals on first and second output ports, the output signal on the first output port including at least a portion of the first branch of the MIMO signal and at least a portion of the second branch of the MIMO signal that is phase shifted orthogonally in relation to the respective second branch of the MIMO signal and the output signal on the second output port including at least a portion of the second branch of the MIMO signal and at least a portion of the first branch of the MIMO signal that is phase shifted orthogonally in relation to the respective first branch of the MIMO signal; at least one master unit communicating with the coupler and configured to receive the output signal from the first output port of the coupler for distributing the output signal to one or more remote units; at least another master unit communicating with the coupler and configured to receive the output signal from the second output port of the coupler for distributing the output signal to one or more remote units; a plurality of remote units communicating with the at least one master unit and a plurality of remote units communicating with the at least another master unit to communicate both the output-signal of the first output port and the output signal of the second output port to a device for providing MIMO communications.
