Abstract

Abstract

The high efficiency in bandwidth and high suppression to sidebands are very meaningful for wireless communications. Based on the composition of its modulated waveforms and power spectra, the optimization to very-minimun waveforms difference keying modulations is put forward, and the advanced modulated waveforms with narrower bandwidth and lower sidebands are obtained.
