Abstract
A highly versatile modulator that uses digital signal processing methods is described. The scheme can realize most known modulations exhibiting diverse forms of signal spectrum and eye diagram, and it can realize a given modulation with extreme precision. A single modulator unit can be host to many forms of modulation, i.e. many forms of signal constellations and spectral shapes. The technique also tends itself very well to very large-scale integration (VLSI) and mass production.<>
