Abstract

"SISTEMA E PROCESSO PARA OCUPAçãO DE PORTADORA ADAPTATIVA EM UM SISTEMA DE ESPECTRO DISTRIBUìDO DE SALTOS DE FREQuêNCIA". é provido um sistema de telecomunicação de espectro distribuído de saltos de freq³ência que seleciona as freq³ências da portadora com base no número de espaços ativos. A duração que essas portadoras empregaram se baseia no número de espaços ativos (401, 402), em vez do número de quadros (22). Assim, espaços que não interferem com as portadoras podem ser usados mais freq³entemente do que aqueles que interferem com as portadoras, aperfeiçoando assim a qualidade da voz.
