OFDM transmission and reception for non-OFDM signals

摘要

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.

主权项

1. A method performed on a computing device that includes at least one processor, memory, a demodulator, and radio hardware, the method comprising:
receiving, via the radio hardware, a non-Orthogonal Frequency-Division Multiplexing (“OFDM”) radio signal and an actual OFDM radio signal, where the received actual OFDM radio signal is channelized over a first plurality of subchannels of an available channel bandwidth: processing, by the at least one computing device, the received non-OFDM radio signal into a created OFDM radio signal that is channelized over a second plurality of subchannels of the available channel bandwidth: demodulating, via the demodulator, the created OFDM radio signal along with the received actual OFDM radio signal, where a width of each of the first and second pluralities of subchannels is based on the non-OFDM radio signal.
