Latest Patents
Yi Cai holds a patent for an "Error mitigation system using line coding for optical WDM communications." This invention discloses an apparatus and method of line coding designed to mitigate collision-induced errors in WDM optical communications systems. The system effectively prevents Soliton-Soliton-Collision induced errors by reducing the variance in the number of possible collisions between solitons across multiple channels. Utilizing a sliding window criterion, the invention defines a set of parametric values based on the physical properties of the transmission network, transmission frequency, and a defined data block size. N-bit codes are iteratively selected and assigned to segments of a mapping table indexed by all unique combinations of '1's and '0's in a data block. This innovative approach allows input data blocks to be mapped to corresponding code words with a reduced number of transitions for efficient transmission on fiber optic networks. The received code words are then converted back to a data stream that corresponds to the original input data stream.
