Phase noise removal in a network of radio frequency (RF) repeaters

Patent number: 12149327

Abstract: A wireless communication system includes a first communication device and a second communication device. The first communication device comprises a first digital signal processor (DSP) that obtains a plurality of radio frequency (RF) signals corresponding to different communication protocols from a plurality of communication systems. The first DSP upconverts a frequency of each of the plurality of RF signals to a different frequency. The first DSP maps and aligns the plurality of RF signals corresponding to the different communication protocols in the mmWave RF signal based on a number of source antennas from which the plurality of RF signals are obtained. Furthermore, the first DSP multiplexes the plurality of RF signals corresponding to different communication protocols into a mmWave RF signal of a specified frequency. The first DSP further transmits the mmWave RF signal of the specified frequency along with a defined pilot tone to the second communication device.
