Filtering involves the application of a filter to a signal or data set. The purpose of filtering is to modify the characteristics of the signal, typically to achieve a desired outcome. Filters can be designed to remove unwanted noise, enhance certain features, or smooth the signal. Filtering is used in various fields, including audio processing, image processing, telecommunications, and control systems.
An ensemble learning algorithm is applied to enhance filtering tolerance of cascaded WSSs in open ROADM environment to demonstrate ~0.8dB Q-factor improvement over MLSE after transmitting over 3200km with 16 ROADMs.
