OFDM transmission and reception for non-OFDMA signals
View Patent ↗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.
1. A method of operating a computing device to accommodate non-Orthogonal Frequency-Division Multiplexing signals (non-OFDM signals), the method comprising:
a) receiving a non-OFDM signal;
b) processing the non-OFDM signal into a created OFDM signal;
c) processing the created OFDM signal;
d) transmitting OFDM and non-OFDM signals; and
e) processing the non-OFDM signals to transmit over a first set of sub-channels, processing the OFDM signals to transmit over a second set of sub-channels and performing an Inverse Fast Fourier Transform (IFFT) of the signals.
2. The method of claim 1 , wherein the method is performed, at least in part, in software defined radio.
3. The method of claim 1 , wherein receiving the non-OFDM signal comprises receiving a wireless signal in a Bluetooth format.
4. The method of claim 1 , further comprising receiving the signals, combining the first and second sets of sub-channels and performing a Fast Fourier Transform (FFT) of the signals from the combined sets of sub-channels.
5. A computer-readable medium having computer-executable instructions, the computer-executable instructions being adapted to perform, when executed, the method of claim 1 .
6. A method of operating a computing device to accommodate non-Orthogonal Frequency-Division Multiplexing signals (non-OFDM signals), the method comprising:
a) receiving a non-OFDM signal by receiving a wireless signal in a Bluetooth format;
b) processing the non-OFDM signal into an OFDM signal to produce a created OFDM signal;
c) receiving an actual OFDM signal by receiving a wireless signal in a WiFi format; and
d) processing the actual OFDM signal with the created OFDM signal.
7. The method of claim 6 , wherein the method is performed, at least in part, in software defined radio.
8. A computer-readable medium having computer-executable instructions, the computer-executable instructions being adapted to perform, when executed, the method of claim 6 .
9. A method of operating a computing device to accommodate non-Orthogonal Frequency-Division Multiplexing signals (non-OFDM signals), the method comprising:
a) receiving a non-OFDM signal;
b) processing the non-OFDM signal into an OFDM signal to produce a created OFDM signal;
c) receiving an actual OFDM signal;
d) processing the actual OFDM signal with the created OFDM signal;
e) transmitting OFDM and non-OFDM signals, processing the non-OFDM to transmit over a first set of sub-channels, processing the OFDM to transmit over a second set of sub-channels and performing an Inverse Fast Fourier Transform (IFFT) of the signals.
