Single-carrier transmission scheme for extracting characteristic parameters of 32-Point 6PolSK-QPSK

EURASIP Journal on Advances in Signal Processing, 2022
Six polarization-shift keying quadrature phase shift keying (6PolSK-QPSK) signal modulation format is formed by different representations of QPSK. A variety of satisfactory single-carrier transmission schemes have been implemented in 24-Point 6PolSK-QPSK.
