Abstract :
We address a specific implementation of frequency hopped, M-ary frequency shift keying (FH/MFSK) combined with an innovative whitening filter and very strong error correction coding. The motivation for this work is to provide reliable acoustic communications in adverse channels which may include severe fading, dynamic noise, jamming, and multi-access interference. The application addressed by this paper involves low power equipment providing robust communications while simultaneously providing low probability of detection by unauthorized interceptors
