Abstract

Disclosed are a method and apparatus for generating a controlled spectrum of modulated energy. A single data stream is splintered into substreams. Each substream is used to modulate a portion of the modulated spectrum. Each substream is transformed into a numerical phase and amplitude representation of a portion of the spectrum to be modulated. The combined numerical representations are then converted to a time-domain representation and filtered to eliminate undesired side-lobes.
