dc.description.abstract	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.	en_US
