Abstract: Methods, systems, and/or devices are provided that permit data transmissions over unused television channels. A method operational in a receiver device, includes monitoring one or more repurposed channels within a television broadcast frequency spectrum for data waveforms, wherein waveforms of different bandwidths coexist within the one or more repurposed channels, and at least a larger waveform has a first bandwidth larger than a channel bandwidth for each repurposed channel. The method also includes receiving a waveform over a repurposed channel from among the one or more repurposed channels, wherein the received waveform has a second bandwidth smaller than the channel bandwidth. The method further includes processing the received waveform by applying a downclocking factor to a clock of the receiver device that causes the receiver device to process the received waveform according to the second bandwidth to obtain a data payload from the received waveform.
