Abstract

APARELHO E PROCESSO PARA COMUNICAÇçO EM BANDAS VARIÁVEIS. A presente invenção refere-se a um transmissor que inclui uma unidade de mapeação configurada para converter dados transmitido em partes de dados associada com subportadoras individuais, uma unidade de conversão de Fourier inversa configurada para converte as partes de dados em um sinal de tempo em série e uma unidade de geração de símbolo configurada para gerar simbolos para rádio-transmissão a partir do sinal de tempo em série. A unidade de mapeação associa o dados transmitido com subportadoras diferentes das subportadoras múltiplas predefinidas dispostas a intervalos regulares em um eixo de frequência. A unidade de desmapeação de um receptor de acordo com a presente invenção fornece dados compreendendo as partes dos dados associadas com subportadoras diferentes das subportadoras múltiplas predefinidas dispostas a intervalos regulares em um eixo de frequência como dados para restauração.
