Parametric Underwater Communications [PDF]
Proceedings of Meetings on Acoustics, 2012 High performance acoustic underwater communications require high bandwidths for high data rates, low carrier frequencies for low channel attenuation and highly directive transducers. These at first sight contradictory requirements can be satisfied by employing parametric arrays. In this way highly directive radiation, which mitigates multipath and thus

Underwater Communication System
International Journal for Research in Applied Science and Engineering Technology, 2023 Abstract: Sensor network have since been considered a promising alternative to complement conventional monitoring processes. These networks are relatively affordable and allow measurements to be taken remotely, in real-time and with minimal human intervention. we are going to use a under -water Wireless sensor network system which can transfer multiple
