Latest Patents

One of his latest patents is titled "Two low complexity decoding algorithms for LDPC codes." This invention presents two improved variants of the reliability-based iterative majority-logic decoding algorithm for regular low-density parity-check (LDPC) codes. The new algorithms introduce a different reliability measure for each check-sum of the parity-check matrix, enhancing the computation of extrinsic information used to update the reliability measure of each received bit in each iteration. The second algorithm includes check reliability that changes at each iteration, achieving considerable error performance gains over standard methods while maintaining low computational complexity.

Another significant patent is "Cycle-based restoration in mesh networks utilizing bandwidth and flow considerations." This invention outlines a two-step method for determining restoration cycles in a mesh network. It involves generating a set of possible restoration cycles and selecting a subset of low-cost cycles based on the availability of capacity on the links. This method accounts for various factors, including traffic class and priority, allowing for targeted improvements in network capacity.
