International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Multi-h CPM has been selected as the Tier II waveform for the Advanced Range Telemetry (ARTM)
program, because it offers 50% better spectral efficiency than Feher-patented FQPSK, which is the
Tier I waveform. Shaped Offset QPSK has been shown to be nearly identical in performance to
Feher-patented FQPSK. Both the Tier I and Tier II waveforms must operate in the presence of
adjacent channel interference in order to meet the range community's telemetry requirements. This
paper presents an experimental characterization of SOQPSK and Multi-h CPM in the presence of
adjacent channel interference, over a range of channel spacings and differential signal amplitudes.
Quantitative results are presented which demonstrate the relative robustness of the ARTM Tier I and
Tier II waveforms, with adjacent channel interference representative of a typical range environment.
