Abstract

a presente invenção refere-se a um sistema de comunicação extensível. o sistema inclui um primeiro módulo para receber um valor de índice de raiz e para gerar uma sequência de autocorrelação de amplitude zero constante com base no valor de raiz. o sistema ainda inclui um segundo módulo para receber um valor de semente e para gerar uma sequência de pseudorruído com base no valor de semente. o sistema ainda inclui um terceiro módulo para modular a sequência de autocorrelação de amplitude zero constante pela sequência de pseudorruído e para gerar uma sequência complexa. o sistema ainda inclui um quarto módulo para traduzir a sequência complexa para uma sequência de domínio de tempo, em que o quarto módulo aplica a deslocamento cíclico na sequência de domínio de tempo para obter uma sequência de domínio de tempo deslocada.
