ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Since the 1970s PCM/FM has been the dominant modulation scheme used for RF telemetry.
However more stringent spectrum availability as well as increasing data rates means that
more advanced transmission methods are required to keep pace with industry demands.
ARTM Tier-I and Tier-II are examples of how the PCM/FM link can be enhanced. However
these techniques require a significant increase in the complexity of the receiver/detector for
optimal recovery.
This paper focuses on a quantitative approach to improving the rate and quality of data using
existing PCM/FM links. In particular ACRA CONTROL and BAE SYSTEMS set themselves
the goal of revisiting the pre-modulation filter, diversity combiner and bit-sync. By
implementing programmable adaptive hardware, it was possible to explore the various
tradeoffs offered by modifying pulse shapes and spectral occupancy, inclusion of forward
error correction and smart source selection. This papers looks at the improvements achieved
at each phase of the evaluation.
