Landslide hazard mapping is important to urban construction and landslide risk management. Dynamic landslide hazard mapping considers landslide deformation with changes in the environment. It can show more details of the landslide process state. Land

The LiNbO3-based polarization controller is widely used, but it needs to be calibrated in order to cancel the remaining birefringence. The calibration of the LiNbO3 polarization controller is untrivial because there are several stages, and for each s

The Volterra series transfer function (VSTF), in which the input-output relationship of a nonlinear system is represented by a series of nonlinear kernel functions, is an elegant tool to model nonlinear systems. The inverse of a nonlinear system can

We propose a regularized sparse recovery (RSR) technique to monitor optical power from the broadened optical spectrum acquired by scanning a tunable optical filter (TOF). The key idea of RSR is to find a smooth but sparse signal spectrum that matches

We discuss implementation aspects of LDPC based soft-decision FEC schemes for high speed optical systems. Several BICM schemes with LDPC convolutional codes are proposed and compared in respects of both performance and implementation complexity.
