Research Institution
The Athena Group will develop an innovative, low-power, fast Fourier transform (FFT) processor for use in mitigating both intentional and unintentional narrowband jamming and interference in handheld global positioning system (GPS) receivers. Athena'sadvanced digital signal processing (DSP) technology is capable of performance levels well beyond those of conventional DSP technologies. Athena will analyze the processing requirements for the GPS receiver application, select an FFT processor configurationalong with pre- and post-FFT 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-specificintegrated 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 marketsegment. Numerous other mass-market FFT ASIC applications, such as asymmetric digital subscriber loop (ADSL) modems and orthogonal frequency division multiplexing (OFDM) wireless communications, also indicate a high market potential for the proposedtechnology.
