Abstract

"SISTEMA DE COMUNICAçõES POR DIFUSãO DE ESPECTRO COM SALTO DE FREQuêNCIA". A presente invenção refere-se a um transceptor de comunicações por difusão de espectro com salto de freq³ência. O transceptor inclui um micro-controlador (110); um transmissor que possui um oscilador de voltagem controlada (122), um sintetizador digital direto (124), e um amplificador de potência (144); e o receptor possuindo um amplificador (146), um misturador, um amplificador IF (132), um bi-modulador (134) e um selecionador de dados (138 ). Quando houver transmissão, o transmissor comunicará um preâmbulo relativo a um predeterminado número de canais preâmbulo, e, então, comunicará grupos de dados de bytes que compreendem um subconjunto de mensagens de dados relativo a uma seq³ência predeterminada de canais de dados. Na recepção, o receptor investiga um predeterminado número de canais preâmbulo para buscar um preâmbulo sendo que cada um dos canais preâmbulos predeterminados está associado a um predeterminado número de canais de dados, em cada seq³ência dos referidos canais de dados. Uma quantidade de bytes que compreende cada grupo de bytes de dados é determinada de acordo com o número de canais na seq³ência dos canais de dados e um predeterminado número de vezes em que cada byte de dados está para ser transmitido.
