An universal digital signal processing (DSP) application for adaptive polarization mode compensation (PMD) compensation was demonstrated in optical transmission systems. In high-speed optical fiber communication systems, it is important to compensate the PMD effectively due to the time-varying and statistical properties of PMD. We designed a low power-consume DSP-based integrated control system to...
This paper demonstrates a universal digital signal processing (DSP) application for adaptive polarization mode compensation (PMD) compensation in optical transmission systems. It is significant and challenging to establish an effective logic control compensator due to the time-varying and statistical properties of PMD, especially in high-speed optical fiber communication systems. We designed a low...
In order to improve the convergent speed of the particle swarm optimization (PSO) algorithm in the control of real-time polarization mode dispersion (PMD) compensation, we apply a new gradient method to PSO algorithm in this paper. We call this new algorithm GTPSO. To compare the convergent speed of PSO and GTPSO algorithm, a test is carried out by searching for the best degree of polarization (DOP)...
This paper describes implementation of a universal digital signal processing (DSP) for adaptive polarization mode compensation (PMD) in optical fiber communication systems. PMD is one of the most difficult issues in implementing high-speed optical communication systems with bit rates of 10 Gb/s or higher. Because PMD possesses the time-varying and statistical properties, to establish an effective...
