Abstract
CHAVAMENTO DE DESLOCAMENTO BIFáSICO CAóTICO DE BANDA ESTREITA. Um sistema (110) e método para transmissão e recepção de sinal pelo chaveamento do deslocamento bifásico caótico 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 radiofrequencia (114) em comunicação de sinal com o codificador de compactação, um decodificador de compactação (124) em comunicação de sinal com o elo de radiofrequencia, 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 bifásico caótico, propagar o sinal transmitido dentro de uma banda de frequencia estreita e receber o sinal propagado substancialmente sem degradação dos dados indicados pelo controle das órbitas do caos.
