摘要:
A wireless communication system includes a first communication device and a second communication device. The second communication device captures over-the-air a mmWave RF signal of a specified frequency having a defined pilot tone transmitted by the first communication device. The second communication device extracts at least one RF signal from a plurality of RF signals corresponding to different communication protocols from the captured mmWave RF signal, estimates phase-noise in the at least one extracted RF signal, and down-converts the at least one extracted RF signal to a source frequency. The second communication device further reduces the phase noise in the at least one extracted RF signal concurrently at the down-convert and utilizes the at least one extracted RF signal with reduced phase noise for further distribution to one or more end-user devices.
