Latest Patents

One of her latest patents is an "Optical coherent receiver with forward error correction." This invention discloses an optical coherent receiver comprising a number of decoding blocks configured to implement iterations of a FEC iterative message-passing decoding algorithm. The decoding blocks are distributed into two or more parallel chains of cascaded decoding blocks. The receiver also includes an intermediate circuit interposed between the two parallel chains. This optical coherent receiver is switchable between a first operating mode, where the intermediate circuit is inactive, and the two parallel chains separately implement the FEC message-passing decoding algorithm on respective client channels, and a second operating mode, where the intermediate circuit is active, allowing the two parallel chains to jointly implement the FEC message-passing decoding algorithm on the same client channel.

Another notable patent is a "Method of decoding a differentially encoded phase modulated optical data signal." This method proposes a way to decode a differentially encoded PSK modulated optical data signal carrying FEC encoded data values. The optical signal is corrected by an estimated phase offset, and from the corrected signal, respective likelihood values for the FEC encoded data values are derived using an estimation algorithm that accounts for the differential encoding rule used for differentially encoding the optical signal. The derived likelihood values are limited to a predetermined range, and from these limited likelihood values, FEC decoded data values are derived using an algorithm that considers the FEC encoding rule.
