Abstract
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.
Claims20
A method performed on a computing device that includes radio hardware, the method comprising:
- dividing, by the computing device, a channel into a plurality of subchannels;
- converting, by the computing device, first data from serial to a first plurality of parallel streams of the first data;
- converting, by the computing device, second data from serial to a second plurality of parallel streams of the second data;
- modulating, by the computing device, the first plurality of parallel streams of the first data and the second plurality of parallel streams of the second data onto the plurality of subchannels of the channel, where the first plurality of parallel streams of the first data is modulated onto a first distinct subset of the plurality of subchannels, and where the second plurality of parallel streams of the second data is modulated onto a second distinct subset of the plurality of subchannels;
- and
- transmitting, by the radio hardware over the channel, a radio signal comprising the modulated first plurality of parallel streams of the first data and the modulated second plurality of parallel streams of the second data.

A computing device comprising:
- at least one processor;
- memory that is couple to the at least one processor and that includes computer-readable instructions that, based on execution by the at least one processor, configure the computing device to perform actions comprising:
- dividing, by the computing device, a channel into a plurality of subchannels;
- converting, by the computing device, first data from serial to a first plurality of parallel streams of the first data;
- converting, by the computing device, second data from serial to a second plurality of parallel streams of the second data;
- modulating, by the computing device, the first plurality of parallel streams of the first data and the second plurality of parallel streams of the second data onto the plurality of subchannels of the channel, where the first plurality of parallel streams of the first data is modulated onto a first distinct subset of the plurality of subchannels, and where the second plurality of parallel streams of the second data is modulated onto a second distinct subset of the plurality of subchannels;
- and
- transmitting, by the radio hardware over the channel, a radio signal comprising the modulated first plurality of parallel streams of the first data and the modulated second plurality of parallel streams of the second data.
