IMPLEMENTATION AND PERFORMANCE OF A HIGHSPEED, VHDL-BASED, MULTI-MODE ARTM DEMODULATORHill, Terrance; Geoghegan, Mark; Hutzel, Kevin; Nova Engineering Inc. (International Foundation for Telemetering, 2002-10)Legacy telemetry systems, although widely deployed, are being severely taxed to support the high data rate requirements of advanced aircraft and missile platforms. Increasing data rates, in conjunction with loss of spectrum have created a need to use available spectrum more efficiently. In response to this, new modulation techniques have been developed which offer more data capacity in the same operating bandwidth. Demodulation of these new waveforms is a computationally challenging task, especially at high data rates. This paper describes the design, implementation and performance of a high-speed, multi-mode demodulator for the Advanced Range Telemetry (ARTM) program which meets these challenges.
