Abstract:
1. A system comprising: circuitry for coupling with a source of a multiple-input and multiple-output (MIMO) signal configured to provide a first branch of a MIMO signal and at least a second branch of the MIMO signal, the branches of the MIMO signal being in the same frequency channel; at least one master unit and a respective plurality of remote units coupled with the master unit, the at least one master unit coupled with the MIMO signal source and configured for providing RF processing of the MIMO signals and for distributing signals to one or more remote units; at least another master unit and another respective plurality of remote units coupled with the another master unit, the another master unit coupled with the MIMO signal and configured for providing RF processing of the MIMO signals and for distributing signals to one or more remote units; a hybrid coupler coupled to receive the first branch of the MIMO signal and the second branch of the MIMO signal on respective first and second input ports and configured to 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; a first plurality of remote units with each remote unit configured for communicating the output signal of the first output port of the hybrid coupler but not the output signal from the second output port from a single antenna coupled with a respective remote unit, the output signal of the first output port including portions of both the first and second branches of the MIMO signal; a second plurality of remote units with each remote unit configured for communicating the output signal of the second output port of the hybrid coupler but not the output signal of the first output port from a single antenna coupled with a respective remote unit, the output signal of the second output port including portions of both the first and second branches of the MIMO signal that are different from the output signal of the first output port; the system configured for communicating both the output signal of the first output port and the output signal of the second output port through the different plurality of remote units with respective single antennas to be used by a device for providing MIMO communications.
