SUPPLEMENTARY NOTESCA: Air Force Flight Test Center Edwards AFB CA CC: 012100 ABSTRACTIn this paper, we develop a new approach which enables adaptation across two modulation schemes in the iNET standard: orthogonal frequency-division multiplexing (OFDM) and shaped-offset quadrature phased-shift keying (SOQPSK). We present the error vector magnitude (EVM) for OFDM and second-order Godard dispersion (D (2) ) for SOQPSK as our link metrics that measure the degradation due to thermal noise and channel effects and then derive the mathematical relationship between these two metrics. This relationship enables us to utilize a set of empirically-derived rules that incorporate both modulation schemes.

A Simulation Testbed for Adaptive Modulation and Coding in Airborne Telemetry

“…A potential improvement to LDAR is to utilize a single channel metric to drive adaptation across both EVM and dispersion. In [17], a mathematical relationship between EVM and dispersion has been derived, allowing us to map a single channel metric to drive adaptation across both SOQPSK and OFDM. This may be a further enhancement of LDAR.…”
