International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / Three Quadrature Phase Shift Keying (QPSK) mapped COFDM systems demonstrating a continuum of
complexity levels are simulated over an evolving three ray model of the multipath fading channel with
parameters interpolated from actual channel sounding experiments. The first COFDM system uses
coherent QPSK and convolutional coding with interleaving in frequency, channel equalization and soft
decision decoding; the second uses convolutional coding with interleaving in frequency, Differential
Phase Shift Keying (DPSK) and soft decision decoding; the third system uses a quaternary BCH code
with DPSK mapping and Error and Erasure Decoding (EED). All three systems are shown to be able to
provide reliable data communication during frequency selective fade events. Simulations demonstrate
QPSK mapped COFDM with reasonable complexity performs well in a multipath frequency selective
fading environment under parameters typically encountered in aeronautical telemetry.
