  • Title:
    Coding for Data Reliability

  • Keywords:

    Error correcting codes, LDPC codes, Data reliability.

  • Description:

    This research topic is focused on techniques for the reliability of information and, in particular, on coding for error correction. Techniques of this type can be designed for application in many specific contexts: among the most interesting ones, in the current scenarios, we can mention 5G/6G cellular networks, where ultra-reliability and very low latency are required, and deep-space systems, where error correcting codes are used to improve the performance of telemetry and telecommand signals. A further, very promising, application concerns the usage of error correcting codes for post quantum asymmetric cryptography where solutions of this kind constitute a valid alternative to other well consolidate schemes. The research consists in designing, analyzing and simulating the behavior of classic and modern, that is, state-of-the-art, error correcting codes, with special emphasis on low-density parity-check (LDPC) codes in their several variants and on different channels or operation conditions.
