Abstract:
Monitoring of optical transmission impairments is achieved by signal processing at the receiver. In an OFDM system spectral properties can be extracted for this purpose in particular. The proposed method, which allows separation of linear and non-linear impairments, is applied in simulation to monitor a number of paths in a small test network.
