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

Patent number: 11283510

Abstract: An network of wireless RF repeaters includes a first communication device and a second communication device. The first communication device obtains a plurality of radio frequency (RF) signals corresponding to different communication protocols from a plurality of communication systems. A frequency of each of the plurality of RF signals is upconverted to a different frequency, which introduces a phase noise in the plurality of RF signals. The plurality of RF signals corresponding to different communication protocols are merged into a mmWave RF signal of a specified frequency and a defined pilot tone is inserted into the mmWave RF signal. The second communication device captures the mmWave RF signal having the defined pilot tone over-the-air. At least one RF signal is down converted to a source frequency and the phase noise in the one extracted RF signal is reduced concurrently based on a reference of the defined pilot tone.
