Title: Oussama Abassi: Innovator in Error-Correcting Codes
Introduction
Oussama Abassi is a notable inventor based in Lorient, France. He has made significant contributions to the field of error-correcting codes, holding two patents that showcase his innovative approaches to data transmission and decoding.
Latest Patents
Abassi's latest patents include a method for decoding non-binary Low-Density Parity-Check (LDPC) codes. This method involves managing a parity-check node calculation unit within an error-correcting code decoder. The decoder is represented as a bipartite graph and is designed to receive two input messages, producing an output message that includes symbols and their associated reliability measures. The process involves initializing multiple FIFO memories with elements derived from the input messages and iteratively determining the output message values.
Another significant patent focuses on transmitting non-binary error-correcting code words using Cyclic Code Shift Keying (CCSK) modulation. This method associates each code word symbol with a sequence of chips and modulates the phase or amplitude of a carrier signal accordingly. The invention utilizes spread spectrum modulation and incorporates a cyclic prefix into each transmitted symbol, enhancing the reliability of data transmission.
