Abstract

In April of 2017 NATO recognized a new standard called JANUS (ANEP-87) that enabled open-access underwater communications to support interoperation of acoustic modems from various manufacturers. The standard was developed over several years primarily at the Centre for Maritime Research and Experimentation (CMRE) in La Spezia, Italy. The key feature of JANUS is the modulation method used in the physical layer communication protocol, employing a form of “frequency hopping” (FH) which sequentially assigns each individual symbol out of the encoder precisely one position in time and frequency.
