Channelizing a wideband waveform for transmission on a spectral band comprising unavailable channel segments

A method, comprising:

• identifying a subset of a plurality of channels of a system bandwidth available for a transmission in a time period, wherein the subset of the plurality of channels is non-contiguous, and wherein each of the plurality of channels has a respective channel bandwidth;
• receiving a first wideband waveform in the time period;
• separating the first wideband waveform into a plurality of waveform segments corresponding to the subset of the plurality of channels;
• de-mapping the plurality of waveform segments based at least in part on the subset of the plurality of channels;
• combining the de-mapped plurality of waveform segments to obtain a second wideband waveform;
• and
• demodulating the second wideband waveform to obtain a stream of bits.

An apparatus, comprising:

• a channel manager configured to identify a subset of a plurality of channels of a system bandwidth available for a transmission in a time period, wherein the subset of the plurality of channels is non-contiguous, and wherein each of the plurality of channels has a respective channel bandwidth;
