Evaluation of the computational effort for chromatic dispersion compensation in coherent optical PM-OFDM and PM-QAM systems.
Recently, coherent-detection (CoD) polarization multiplexed (PM) transmission has attracted considerable interest, specifically as a possible solution for next-generation systems transmitting 100 Gb/s per channel and beyond. In this context, enabled by progress in ultra-fast digital signal processing (DSP) electronics, both multilevel phase/amplitude modulated formats (such as QAM) and orthogon...
متن کاملPerformance of PM QPSK and PM 16-QAM coherent optical fiber communication systems
The performance of polarization multiplexed, quadrature phase shift keying (PM QPSK) and polarization multiplexed 16-ary quadrature amplitude modulation (PM 16-QAM) is considered with an emphasis on the signal processing algorithms that compensate transmission impairments and implement key receiver functions.
متن کاملAlgorithms of Chromatic Dispersion Equalization in Coherent Optical Communication Systems
In order to respond to the technologic society expectations and satisfying the nowadays search of services who required a high spectral efficiency, emerge an interest about coherent optical systems, that allows multi-level modulation formats and digital signal processing. So, the study of performance of equalization algorithms at digital domain is essential in order to get the best solutions. T...
متن کاملEnergy-Efficient Chromatic Dispersion Compensation for Coherent Fiber-Optic Receivers
DSP-based chromatic dispersion compensation accounts for a large part of the overall power dissipation in fiber-optic receiver ASICs. We have implemented and evaluated compensation filters based different design methods using a MATLAB-based coherent fiber-optic system model in respect to compensation performance, filter length, and fixed-point aspects. Possible power savings when taking into ac...
متن کاملChromatic dispersion compensation in coherent transmission system using digital filters.
We present a comparative analysis of three popular digital filters for chromatic dispersion compensation: a time-domain least mean square adaptive filter, a time-domain fiber dispersion finite impulse response filter, and a frequency-domain blind look-up filter. The filters are applied to equalize the chromatic dispersion in a 112-Gbit/s non-return-to-zero polarization division multiplexed quad...
