Abstract

SISTEMA DE COMUNICAçãO SUBAQUáTICA, SISTEMA DE NAVEGAçãO SUBAQUáTICA E SISTEMA DE POSICIONAMENTO SUBAQUáTICO apresenta um sistema forte de comunicação subaquática para comunicação entre um transmissor de sinal acústico e um receptor de sinal acústico posicionado de modo remoto, caracterizado pelo fato que os dados transmitidos são levados por uma pluralidade de símbolos, cada um tendo dois componentes, um dos quais compreende um código em binário distinto e o outro pertence ao caractere do símbolo como um todo, caracterizado pelo fato que o caractere dos símbolos sucessivos é colocado através de uma seqüência de repetição contínua pré-determinada de etapas distintas cada qual ocorrendo uma vez na seqüência, o sinal receptor sendo operado de modo sincrónico com o sinal transmissor e compreendendo um arranjo co-relator responsivo tanto ao código binário quando ao caractere de sinais recebidos para efetuar a desmodulação e tendo uma pluralidade de saídas, uma para cada símbolo, de modo que conforme cada símbolo é detectado, um sinal na saía a qual este corresponde predomina e o detector de amplitude significa uma resposta às saídas do arranjo corelato para apresentar um sinal de saída correspondente aos dados transmitidos.
