Abstract

"SEQüêNCIAS DE SALTOS DE FREQüêNCIA PARA SISTEMAS DE COMUNICAçãO MULTIBANDA". Técnicas para gerar seqüências FH tendo excelentes propriedades de correlação e utilizar essas seqüências FH em sistemas de comunicação multibanda (por exemplo, sistemas OFDM). Em um aspecto, seqüências FH podem ser geradas com base em uma expressão algébrica y(k)=log<244>b/k(mod p), onde k é um índice, p é um número primo ímpar, <244> é uma raiz primitiva de p, b é um número inteiro; e (mod p) denota operação de módulo-p. Seqüências FH diferentes podem ser geradas com diferentes valores para b, <244>, e/ou p. Em um outro aspecto, os dados podem ser transmitidos utilizando seqüências FH geradas com base na expressão y(k)=log<244>b/k(mod p). Em um primeiro esquema, os dados podem ser transmitidos em canais de 'tráfego', cada um dos quais pode ser associado a uma seqüência FH respectiva que determina a sub-banda específica a ser utilizada em cada partição. Em um segundo esquema, cada transmissão de dados é enviada em sub-bandas determinadas com base em toda, ou em uma porção de, uma seqüência FH.
