A Hardware Implementation of a Coherent SOQPSK-TG Demodulator for FEC Applications
… phase shift keying, telemetry group version (SOQPSK-TG) for use in forward error correction (FEC) applications. Implementation details for data sequence detection, symbol timing synchronization, carrier phase synchronization, and block recovery are described. This decision-directed demodulator …

Equalization Techniques For Multipath Mitigation in Aeronautical Telemetry
… two compatible offset QPSK waveforms (FQPSK and SOQPSK-TG) that constitute the ARTM Tier-1 waveforms. An adaptive version of the DF-MMSE equalizer is developed and applied to this application. In the presence of frequency selective multipath interference typically encountered in aeronautical …

Space-Time Coding with Offset Modulations
… QPSK (FQPSK-JR) and shaped offset QPSK (SOQPSK-TG) can be interpreted as both cross-correlated, trellis-coded quadrature modulation (XTCQM) and continuous phase modulation (CPM). Based on these representations, both modulations can be detected with near optimal bit error rate performance …
