Mode division multiplexed(MDM) in few mode fibers has gained attraction due to its potential to achieve ultrahigh capacity beyond the nonlinear Shannon limit of the single mode fiber. However, it cannot be ignored that the effect of crosstalk, mode coupling and differential mode group delay on optical signals exists in transmission and equalizing these impairments are required in the digital signal...
Twice real-valued FastICA (TR-FastICA) algorithm is proposed in this paper to eliminate crosstalk between the two polarization multiplexed complex-valued higher-order quadrature modulation format such as QPSK signals induced by polarization mode coupling with polarization mode dispersion (PMD) and polarization dependent loss (PDL) for the coherent optical polarization division multiplexing (CO-PDM)...
In this paper, we present implementation of an infinite impulse response (IIR) adaptive filter with particle swarm optimization (PSO) on field programmable gate array (FPGA). Particle swarm optimization performs a structured randomized search of an unknown parameter space by manipulating a population of parameter estimates to converge on a suitable solution. And this technique is independent of the...
