Abstract:
An embodiment of a transmitter includes detection, generating, and transmission stages. The detection stage is configured to detect a first signal having a first component that includes a frequency, and the generating stage is configured to generate a data component that includes approximately the frequency in response to the detection of the first signal. The transmission stage is configured to transmit a second signal having the data component while the detection stage is detecting the first signal. For example, two or more such transmitters (e.g., two or more smart phones) may simultaneously transmit OFDM signals on the same subcarrier frequencies and over the same channel space. By allowing the simultaneous transmission of multiple signals on the same frequencies and over the same channel space, such a transmitter may increase the effective bandwidth of the channel space, and thus may allow more devices to simultaneously share the same channel space.
