Under Water Wireless Communication using Matlab with Modem
Objective
A Simulink model for IDMA-OFDM is presented. Its performance was observed on BER graph which displayed a BER v/s SNR plot.
Abstract
Cellular communication over earth is far different than communication underwater because a single water body like an ocean has different water columns existing throughout its regions. A transmitter-receiver pair developed to work at deep sea level won’t work in shallow coastal regions because the properties of water column present between the transmitter-receiver will be completely different and vice-versa. The diversity of water bodies is what makes the implementation of communication link more challenging. As of now Acoustics is the most promising method employed to establish UWC link. But this method is hindered by multipath phenomenon which introduces a large delay spread. This in turn will result in Inter symbol Interference (ISI) consequently degrading the system’s performance. Employing OFDM technique will reduce the delay spread. OFDM paired with IDMA provides a superior technique to reduce error bursts in multi-access underwater applications. A Simulink model for IDMA-OFDM is presented in this paper. Its performance was observed on BER graph which displayed a BER v/s SNR plot.
Keywords: underwater communication, wireless, Orthogonal Frequency Division Multiplexing (OFDM), Interleave Division Multiple Access (IDMA).
