Abstract

"CHAVEMENTO DE DESLOCAMENTO DE FREQUêNCIA CAóTICA DE BANDA ESTREITA" Um sistema (110) e método para transmissão e recepção de sinal pelo chaveamento do deslocamento de freq³ência caótica de banda estreita inclui um codificador de correção de erro avançado (118) para receber os dados de entrada, um empacotador de dados (120) em comunicação de sinal com o codificador de correção de erro avançado, um codificador de compactação (122) em comunicação de sinal com o empacotador de dados, um elo de radiofreq³ência (114) em comunicação de sinal com o codificador de compactação, um decodificador de compactação (124) em comunicação de sinal com o elo de radiofreq³ência, um desempacotador de dados (126) em comunicação de sinal com o decodificador de compactação e um decodificador de correção de erro avançado (128) em comunicação de sinal com o desempacotador de dados para recuperar os dados de entrada controlando as órbitas do caos; onde o método inclui as etapas de transmitir um sinal indicativo dos dados chaveados do deslocamento de freq³ência caótica, propagar o sinal transmitido dentro de uma banda de freq³ência estreita e receber o sinal propagado substancialmente sem degradação dos dados indicados pelo controle das órbitas do caos.
