Abstract

SISTEMA DE RáDIO DE ESPECTRO EXPANDIDO HìBRIDO. A presente invenção refere-se a sistemas e métodos para os sistemas de rádio de espectro expandido híbrido. Um método inclui modular um sinal pela utilização de um subconjunto de bits de um gerador de código pseudo-randõmico para controlar um circuito de amplificação que provê um ganho para o sinal. Outro método inclui: modular um sinal pela utilização de um subconjunto de bits de um gerador de código pseudo-randómico para controlar um sintetizador de frequência de salto rápido; e saltar em frequência rápido o sinal com o sintetizador de frequência de salto rápido, em que múltiplos saltos de frequência ocorrem dentro de um único tempo de bit de dados.
