Sharoar Jahan Jahan, Ishrat We are highly grateful and indebted to our supervisor, Dr. Satya Prasad Majumder, Professor, Department of Electrical Electronic Engineering, Bangladesh University of Engineering & Technology (BUET), for his continuous guidance, supervision, encouragement and untiring support throughout this work. Additionally, we would like to express our sincere thanks to all other Teachers and staffs of the Department of Electrical, Electronic & Communication Engineering, Military Institute of Science & Technology (MIST) for their co-operation and help in the successful completion of this work. Our thanks would also go to our beloved family for their prayer, encouragement and support to achieve our goals. An analytical development on a Circular Polarization Division Multiplexing (CPDM) Quadrature Phase Shift Keying (QPSK) based optical transmission system with coherent homodyne detection is carried out in order to maximize the spectral efficiency of Fiber Optic transceivers by assessing the Bit Error Rate (BER) performance of the system considering the crosstalk induced by cross-polarization (XPol). Considering Maxwell- Boltzman distribution for the probability distribution function (pdf) of the misalignment angle, the average BER is derived. This analysis is extended to find the BER and Signal to Crosstalk plus Noise Ratio (SCNR) considering the power penalty due to different mean misalignment angle. Results show that the system suffers significant deterioration in BER performance and power penalty due to XPol-induced crosstalk. Penalty in signal power is found to be 6.43, 16.78, 31.99 and 76.99 dB for mean misalignment angle of 20, 30, 40 and 60 degree respectively. CPDM inherently operates QPSK to increase the bit rate within the same spectral width of the transmitter. So, the outcome of this research can be an effective candidate to upgrade the design of the existing optical polarization diversity PDM coherent transmission systems. 2019-03-10T03:52:40Z 2019-03-10T03:52:40Z 2017-12 Thesis http://hdl.handle.net/123456789/412 en application/pdf DEPARTMENT OF ELECTRICAL, ELECTRONIC AND COMMUNICATION ENGINEERING |
