This paper focuses on reducing the complexity of Twin-SSB system and further enhancing the spectral efficiency by proposing a polarization division multiplexing (PDM) Twin-SSB modulation scheme. LSB and RSB signals are extracted using de-mapping algorithm instead of optical bandpass filters (OBPFs) to reduce system complexity. To further improve spectral efficiency, PDM is employed to meet the polarization multiplexing transmission and achieve a higher transmission capacity. Based on the PDM Twin-SSB system, the LSB is 3-arr phase-shift-keying (3PSK) modulated, while RSB is quadrature phase-shift keying (QPSK) modulated. We simulated that the bit error ratio (BER) performance of LSB and RSB of X-polarization (X-Pol) and Y-polarization (Y-Pol) at 8-Gbaud, 10-Gbaud, 12-Gbaud, 14-Gbaud, and 16-Gbaud in the case of back-to-back (BTB) and 2 km standard single-mode fiber (SSMF) transmission. The simulation results verify the effectiveness and practical feasibility of the proposed PDM Twin-SSB scheme for future short-distance transmission owing to low cost, simplified structure, low algorithm complexity, and high data transmission capacity.<\/jats:p>","DOI":"10.3390\/s22207700","type":"journal-article","created":{"date-parts":[[2022,10,11]],"date-time":"2022-10-11T06:13:27Z","timestamp":1665468807000},"page":"7700","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Optical Polarization Division Multiplexing Transmission System Based on Simplified Twin-SSB Modulation"],"prefix":"10.3390","volume":"22","author":[{"given":"Ye","family":"Zhou","sequence":"first","affiliation":[{"name":"School of Optical Electrical and Computer Engineer, University of Shanghai for Science and Technology, Shanghai 200093, China"}]},{"given":"Jun","family":"Ming","sequence":"additional","affiliation":[{"name":"School of Optical Electrical and Computer Engineer, University of Shanghai for Science and Technology, Shanghai 200093, China"}]},{"given":"Leilei","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Optical Electrical and Computer Engineer, University of Shanghai for Science and Technology, Shanghai 200093, China"}]},{"given":"Dongyan","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Optical Electrical and Computer Engineer, University of Shanghai for Science and Technology, Shanghai 200093, China"}]},{"given":"Li","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Information Science and Technology, Fudan University, Shanghai 200433, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2923-4287","authenticated-orcid":false,"given":"Jiangnan","family":"Xiao","sequence":"additional","affiliation":[{"name":"School of Optical Electrical and Computer Engineer, University of Shanghai for Science and Technology, Shanghai 200093, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1994","DOI":"10.1093\/ietcom\/e88-b.5.1994","article-title":"Performance analysis of optical single sideband modulation based on Mach-Zehnder interferometers and its dispersive fiber transmission","volume":"88","author":"Takano","year":"2005","journal-title":"IEICE Trans.
