Abstract
A multiple-input multiple-output (MIMO) capable system is contemplated. The communication system may include a signal processor configured to separate an input stream into multiple signal paths to facilitate simultaneous transport through a communication medium. The capability to simultaneously transmit multiples signal paths may be beneficial in order to maximize throughput and/or minimize expense.
Claims20
A multiple-input multiple-output (MIMO) user equipment (UE) comprising:
- a front end configured to process at least a first signal part, a second signal part, a third signal part and a fourth signal part;
- a radio frequency integrated circuit (RFIC) configured to convert the first signal part at a first frequency, the second signal part at a second frequency, the third signal part at a third frequency and the fourth signal part at a fourth frequency to a common fifth frequency;
- and
- a baseband processor configured to combine the first, second, third and fourth signal parts into an output signal.
A multiple-input multiple-output (MIMO) user equipment (UE) operable with a hybrid fiber coaxial (HFC) network to facilitate wireless and wireline signaling, the UE comprising:
- a front end having a wireline interface for interfacing wireline signals with the HFC network and a wireless interface for interfacing wireless signals with the HFC network, the front end including wireless and wireline signal paths for the interfaced wireless and wireline signals;
- a radio frequency integrated circuit (RFIC) configured to generated frequency converted signals for the wireline and wireless signal paths;
- and
- a baseband processor configured to interface the frequency converted signals with a device connected thereto.
A multiple-input multiple-output (MIMO) user equipment (UE) operable with a hybrid fiber coaxial (HFC) network to facilitate processing downlink spatial diverse wireless signaling generated from frequency diverse wireline signal transmitted over a wired communication medium of the HFC network, the UE comprising:
- a front end having a plurality of wireless ports for receiving the spatially diverse wireless signals;
- a radio frequency integrated circuit (RFIC) configured to frequency convert signals output from the front end as a function of the received wireless signals received to a common frequency;
- and
- a baseband processor configured to interface the frequency converted signal with a device connected thereto.
