Circuits and method to enable efficient generation of direct digital synthesizer based waveforms of arbitrary bandwidth

摘要

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.

1. A method for providing wideband inverse channelization for direct digital synthesizer based jamming, comprising:
selecting metadata of at least one of a plurality of jamming techniques using a time commute multiplexer, the plurality of jamming techniques comprising different metadata associated with jamming for generating a waveform, the selected metadata comprising frequency, phase and amplitude parameters and free from raw data specific to the at least one of a plurality of jamming techniques; generating a reference frequency at a frequency generator based on the frequency parameter; generating data select signals and data input based on the selected metadata and the reference frequency; providing the data select signals and data input to a first de-multiplexer and a second de-multiplexer; and producing in-phase and quadrature signals at an output of the first de-multiplexer and the second de-multiplexer, respectively, based on the data select signals and the data input.
