Device and method for digital vestigial sideband modulation

摘要

A digital signal processing device and method for vestigial sideband (VSB) modulation of a digital signal. A binary digital signal di is provided to a baseband shaping filter which samples the signal to provide a baseband signal which has real and imaginary portions Re(Sbb(kT)) and Im(Sbb(kT)), where $The\; VSB\; signal\; is\; provided\; with\; perfect\; sideband\; suppression\; without\; using\; analog\; filters.$
