Abstract

"NOVA ARQUITETURA DE TRANSCEPTOR ANALóGICO DE BAIXO CUSTO/BAIXA POTêNCIA". Um transceptor de banda lateral única (SSB) de Divisão de Freq³ência Duplex (TDD) inclui um transmissor adaptado para dar entrada a um sinal de áudio analógico, amostrar o sinal de áudio analógico e dar saída a um sinal modulado por deslocamento de freq³ência SSB correspondente ao sinal de áudio analógico, o sinal FSK SSB incluindo informação analógica. Um receptor é adaptado para comutar entre receber ou a banda lateral superior ou a banda lateral inferior de um sinal SSB externo.
