On modeling JANUS packet errors over a shallow water acoustic channel using Markov and hidden Markov models
2010
2010 - MILCOM 2010 MILITARY COMMUNICATIONS CONFERENCE
Preserved Fulltext
In this paper, we investigate how to represent the packet error process in a shallow water acoustic channel by means of Markov as well as hidden Markov models. ...
In particular, signal-to-noise ratio (SNR) time series show significant transitions of the average SNR on a large time scale, which motivates the use of hidden Markov models. ...
We considered Markov models with memory of both one and two past events, and a hidden Markov model (HMM), and compared them to data traces and a simpler iid error model. ...
