Abstract

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Effectiveness of Convolutional Code in Multipath Underwater Acoustic Channel

“…Channel coding schemes such as convolutional code (CC) and Reed Solomon (RS) block code with Viterbi decoder, were also implemented to compensate multipath interference and underwater noise. [8][9][10][11] The data rates in underwater acoustic communication are classified as 100-1000 bit/s for command/control of navigation and equipment status, 1-10 kbit/s for acoustic instruments such as hydrophones and seismometers, and 10-100 kbit/s for underwater video image. 12) Therefore, in low data rate of 100-1000 bit/s which has a narrow signal bandwidth, frequency non selective system without the equalizer could be designed in shallow water multipath fading channel.…”
