Common detectors for shaped offset QPSK (SOQPSK) and Feher-patented QPSK (FQPSK)
@article{Nelson2005CommonDF, title={Common detectors for shaped offset QPSK (SOQPSK) and Feher-patented QPSK (FQPSK)}, author={Tom Nelson and Erik S. Perrins and Michael D. Rice}, journal={GLOBECOM '05. IEEE Global Telecommunications Conference, 2005.}, year={2005}, volume={6}, pages={5 pp.-3747} }
Symbol-by-symbol detection of SOQPSK and FQPSK using detectors designed for offset QPSK represents a simple common detector architecture for these two interoperable waveforms. Unfortunately, this detection method results in a 2 dB loss in bit error rate performance. This paper describes detection methods for recovering this loss without the need for knowing which modulation is used by the transmitter. An equivalent cross-correlated trellis-coded quadrature modulation (XTCQM) representation for…
