In-situ performance prediction of a coherent acoustic modem

A channel sounding and communications experiment was performed in the Oslofjord in April/May 2019, where 8 bottom units were deployed in a network configuration. Five units were equipped with a software-defined acoustic modem operating in the 4–8 kHz band, programmed to transmit probe signals and communication packets. All transmitted signals were recorded by all units over 35 unique horizontal li...
