Claim:
1. A method, comprising: receiving, at a receiver, a Filter-Bank Multi-Carrier Spread-Spectrum (FB-MC-SS) signal as an underlay control channel having a power level below an apparent noise level for other signals of a frequency spectrum, wherein the FB-MC-SS includes at least one data symbol redundantly modulated onto each subcarrier of the FB-MC-SS signal such that each subcarrier includes the same at least one data symbol; demodulating, with a demodulator of the receiver, the FB-MC-SS signal to generate a baseband signal; and extracting, with an analysis filter bank of the receiver, a received signal from each subcarrier of the baseband signal by performing an inverse process of a synthesis filter bank of a transmitter that generated the FB-MC-SS signal.
