Abstract:
A microwave transmit system is provided that makes use of optical fiber to convey a microwave frequency source. A local oscillator produces a microwave frequency source in electrical form. A directly modulated laser receives the first microwave frequency source and produces an optical signal. An optical fiber is used to convey the optical signal from the laser to a photodetector. The photodetector receives a first component of the optical signal and converts the first component of the optical signal to a second microwave frequency source in electrical form. A microwave modulator performs microwave modulation using the second microwave frequency source, and a microwave antenna configured to transmit an output of the first microwave modulator. For MIMO operation, there can be a second microwave modulator. The microwave frequency source can also be conveyed to the second microwave modulator using optical fiber, or the source can be proximate to one of the two microwave modulators, and conveyed to the other of the two microwave modulators using optical fiber.

Claim (Index 18):
The method of  claim 17  wherein performing MIMO processing comprises:\n demultiplexing the input data stream into first and second data streams; \n MIMO precoding the first and second data streams to produce first and second MIMO precoded outputs; \n wherein the first and second MIMO components are the first and second MIMO precoded outputs.
