Single-Carrier Transmission Scheme for Extracting Characteristic Parameters of 32-Point 6PolSK-QPSK [PDF]
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.

A Novel 32-Point Modulation Scheme of 6PolSK-QPSK Signal
IEEE Access, 2023 The six-polarization shift keying quadrature (6PolSK-QPSK) has been proved to be an alternative to four-dimensional (4D) modulation scheme. A variety of transmission compensation schemes have been developed for 24-Point 6PolSK-QPSK combining the ...

Modulation Schemes of 6PolSK-QPSK in Repeaterless Transmission System
Asia Communications and Photonics Conference 2021, 2021As a combination of PM-QPSK and PS-QPSK, 6PolSK-QPSK has better spectral efficiency. A modulation scheme is proposed to generate 6PolSK-QPSK signal transmission, constructs VPI system structure, and realizes the 40Gbps data transmission in this paper.

Constant Envelope OFDM Scheme for 6PolSK-QPSK
Optics Communications, 2018Abstract A constant envelope OFDM scheme with phase modulator (PM-CE-OFDM) for 6PolSK-QPSK modulation was demonstrated. Performance under large fiber launch power is measured to check its advantages in counteracting fiber nonlinear impairments. In our simulation, PM-CE-OFDM, RF-assisted constant envelope OFDM (RF-CE-OFDM) and conventional OFDM (Con ...

Investigation of Quadrature Imbalance Compensation Algorithm for Coherent 6PolSK-QPSK
Physical Communication, 2017Abstract 6PolSK-QPSK is a promising modulation format in optical fiber communication. Because of the damage suffered during the transmission and reception, a series of algorithms are needed to be adopted to recover the original data. We proposed a novel quadrature imbalance compensation algorithm based on the data statistical properties.

PS-QPSK is the most power efficient modulation formats in coherent transmission systems. (6PolSK)-QPSK not only benefits from PS-QPSK but also offers a better spectral efficiency. A novel scheme of 6PolSK-QPSK modulation is proposed and the performance of (6PolSK)-QPSK is compared to that of (PDM)-QPSK and PS-QPSK.

Generation of 6PolSK-QPSK Using Dual-Drive Mach-Zehnder Modulators
Asia Communications and Photonics Conference 2014, 2014We propose a 6PolSK-QPSK transmitter scheme, which is based on one DD-MZM in each polarization component. This transmitter scheme simplifies optical components and each DD-MZM is driven by two independent four-levels electrical signals with peak-to-peak drive voltage of 3Vn/2, which is considerable in practical realization.

Nonlinear Transmission of 6PolSK-QPSK Signals Using Coded Modulation and Digital Back Propagation
Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013We experimentally investigate the characteristics of 126-Gb/s coded 6PolSK-QPSK signals in the nonlinear transmission regime and demonstrate that required OSNR improvement is increasing with fiber-launch power due to coded modulation as well as digital back propagation.
