This paper reports measurements for ultrasonic underwater acoustic communication (UAC) channels in Mediterranean shallow waters performed by the company SAES and the research group Ut2 of the University of Málaga.
Statistical fit to the measured data is also carried out. The measurements have been conducted when the transmitter and the receiver are spaced 50, 100 and 200 m, approximately. Both transducers (B&K 8105 and RESON TC4032) have been placed at depths 3, 6 and 9 m from anchored boats. Faded channel sounding signals have been recorded at frequencies 32, 64 and 128 kHz.
After preprocessing the measured data, accurate statistical fit to the recently proposed κ-μ shadowed fading model is obtained; this model includes, among others, the Rayleigh, Ricean and Nakagami-m fading.
