Methods and apparatuses for Orthogonal Frequency-Division Multiplexing
(OFDM) communication of non-OFDM radio signals are disclosed. The
non-OFDM radio signals are force-modulated into OFDM signals. In one
example, a non-OFDM signal is received and is processed into an OFDM
signal to produce a created OFDM signal. An actual OFDM signal is also
received and is processed together with the created OFDM signal.
