A low-complexity low-latency interactive communication system with spectral efficiency approaching the Shannon limit

BackgroundDigital communication systems use forward error correction (FEC) in order to be spectrally efficient and approach the Shannon limit. The drawbacks of using FEC are high latency and high computational complexity. On the other extreme, commun Read More >

Free online web wizard application to assess the amount of nonlinear interference noise generated in fiber-optic communications systems

Nonlinear interference noise (NLIN) is arguably the most important factor limiting the capacity of fiber-optic communication systems. It is customary to classify nonlinear phenomena as either intra-channel, or inter-channel. Intra-channel effects rel Read More >
