AN ENHANCED, CONSTANT ENVELOPE, INTEROPERABLE SHAPED OFFSET QPSK (SOQPSK) WAVEFORM FOR IMPROVED SPECTRAL EFFICIENCY

International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / Shaped BPSK (SBPSK) and Shaped Offset QPSK (SOQPSK), as defined in various MIL standards, are
widely employed on SATCOM links because they offer an attractive combination of good spectral
efficiency, constant envelope characteristics, and interoperability with legacy equipments. More
recently, numerous terrestrial applications of OQPSK and similar waveforms (Feher-patented FQPSK)
have been proposed. The present paper describes a simple non-proprietary modification of the MIL-STD
SOQPSK waveform which offers spectral containment and detection efficiency comparable to or better
than FQPSK-B (Revision A1), while preserving a constant envelope characteristic and backward
compatibility with existing equipment.
