Abstract
Embodiments of a system and method for providing efficient wideband inverse channelization for direct digital synthesizer based jamming techniques are generally described herein. In some embodiments, metadata associated with a technique for generating a waveform, such as frequency, phase and amplitude parameters, is received. Data select signals and data input are generated based on the received metadata. In-phase and quadrature signals are produced at an output of a first de-multiplexer and a second de-multiplexer, respectively, based on the data select signals and the data input. Frequency modulated signals generated by direct digital synthesizers may be combined in a channel using a separate, distinct channel combiner.
