Abstract
"GERADOR DE SALTOS DE FREQUêNCIA PARA USO EM UMA REDE DE COMUNICAçãO SEM FIO, E, PROCESSO PARA USO EM UMA REDE SEM FIO DE SALTOS DE FREQUêNCIA" Um gerador de saltos de frequência compreende um módulo de processamento XOR e um módulo de processamento PERM (permutação) dispostos em série. Os módulos XOR e PERM atuam diretamente sobre linhas de relógio de entrada em função de um endereço de seleção. A sequência de número de saltos gerada pelo gerador de saltos de frequência pode ser alterada em tempo real variando os endereços de seleção, enquanto que a fase da sequência pode ser trocada em tempo real pela alteração do valor de relógio sobre a linhas de relógio. O gerador de frequência encontra aplicação típica no rapidamente comutar entre diferentes picomalhas em uma rede de dispersão sem fio.
