Issue Date: | 9-Apr-2012 | Citation: | Zhang, H., Kam, P.-Y., Yu, C. (2012-04-09). Performance analysis of coherent optical 8-star QAM systems using decision-aided maximum likelihood phase estimation. Optics Express 20 (8) : 9302-9311. ScholarBank@NUS Repository. https://doi.org/10.1364/OE.20.009302 | Abstract: | An approximate bit-error rate (BER) expression of 8-star quadrature amplitude modulation (QAM) in the presence of a phase estimation error is derived. The accuracy of the approximate BER is verified via numerical integration of the conditional BER and the Monte-Carlo (MC) simulations. This approximation allows quick estimation of the BER performance and prediction of laser linewidth tolerance, and also facilitates optimization of the ring ratio. © 2012 Optical Society of America. | Source Title: | Optics Express | URI: | http://scholarbank.nus.edu.sg/handle/10635/57013 | ISSN: | 10944087 | DOI: | 10.1364/OE.20.009302 |
