AbstractThe Advanced Range Telemetry (ARTM) program was launched in the late nineties to alleviate a shortage of telemetry spectrum through the development of new modulation techniques with higher spectral efficiency. The ARTM program delivered two new families of modulation techniques (Tier I and Tier II), offering 2 to 2.5 times the spectral efficiency of PCM/FM, respectively. Despite these very substantial gains in spectral efficiency, the ARTM Tier I and Tier II waveforms are not yet in widespread use in the telemetry community. The adoption of these new modulation techniques has been slowed by concerns over the robustness of the demodulators for these waveforms. Increasing the utilization of the Tier I and Tier II waveforms requires the development of demodulators which offer the robust performance of the traditional non-coherent Tier 0 demodulators which have earned the confidence of the flight test community over the past three decades. This is the purpose of the proposed Noncoherent Telemetry Demodulator (NTD) program..
