Underwater communication with IDMA scheme

Abstract

Underwater communication finds numerous application including oceanographic data collection, pollution, monitoring, offshore exploration, disaster prevention, assisted navigation, tactical, surveillance, and mine reconnaissance. The enabling technology for these applications is acoustic wireless networking. A major challenge for the deployment of UW-ASN is the development of a multipleaccess technique and modulation technique tailored for the underwater environment. Typical frequency ranges from 1 Hz to 1 MHz resulting in low data rates. The ever-increasing demand of short- and long-distance communication is leading to further research in the field of underwater communication. In this paper, performance analysis has been done for underwater acoustic (UWA) communication with IDMA scheme using BPSK modulation techniques. fThe simulated system is subjected to additive white Gaussian noise (AWGN) in the channel in uncoded environment using random interleavers in MATLAB environment.
