ADEPT: Athena Digital Excision Processor Technology

"The Athena Group, Inc. will develop an innovative, low-power, fast Fourier transform (FFT) and inverse FFT (IFFT) processor for use in mitigating both intentional and unintentional narrowband jamming and interference in handheld global positioning system(GPS) receivers. Athena's advanced digital signal processing (DSP) technology is capable of performance levels well beyond those of conventional DSP processing technologies. Athena will analyze the processing requirements for the GPS receiver application,select an FFT/IFFT processor configuration along with supervisory processing elements, and analyze the resulting design for speed, power, and hardware requirements. The proposer will optimize a solution that will lead to a commercial system-on-chip (SoC)anti-jam GPS application-specific integrated circuit (ASIC) implementation. The commercial value of the developed technology is substantial since it will significantly improve the reliability and quality of GPS service. GPS applications are proliferating,especially in the land-based market segment. Numerous other mass-market FFT ASIC applications, such as asymmetric digital subscriber loop (ADSL) modems, orthogonal frequency division multiplexing (OFDM) wireless communications, and co-channel interference(CCI) rejection for wireless communications also indicate a high commercial potential for the proposed technology."
