1. A wireless communication system, comprising:
a first communication device and a second communication device, wherein the first communication device comprises a first digital signal processor that is configured to:
obtain a plurality of radio frequency (RF) signals corresponding to different communication protocols from a plurality of communication systems;
upconvert a frequency of each of the plurality of RF signals to a different frequency, wherein the upconversion introduces a phase noise in the plurality of RF signals;
map and align the plurality of RF signals corresponding to the different communication protocols in a mmWave RF signal based on a number of source antennas from which the plurality of RF signals are obtained;
multiplex the plurality of RF signals corresponding to the different communication protocols into the mmWave RF signal of a specified frequency; and
transmit the mmWave RF signal of the specified frequency along with a defined pilot tone to the second communication device, wherein the mmWave RF signal is captured by the second communication device to extract at least one RF signal from the plurality of RF signals and down-convert the at least one extracted RF signal to a source frequency associated with the plurality of communication systems.
