Abstract
Systems, transmitters, and methods employing waveform bandwidth compression to transmit information are provided. Transmitters may include an encoder to generate a time-domain amplitude sequence from information in a constant amplitude sinusoidal modulation format; fit a polynomial to the time-domain amplitude sequence, the fitted polynomial spanning at least one transmission time interval; and convert the polynomial to a transmission signal, the transmission signal comprising a sum of sinusoids of differing frequencies, each sinusoid having a continuously time-varying amplitude. A carrier source providing a carrier that is modulated with the transmission signal and transmitted through the system to a receiver, which receives the signal in the constant amplitude sinusoidal modulation format. The sum of sinusoids of differing frequencies having a continuously time-varying amplitude may be generated using instantaneous spectral analysis, to reduce the spectral occupancy of the transmission signal.
