Abstract
Patente de Invenção: "APARELHO DE COMUNICAçãO DE RáDIO E MéTODO DE COMUNICAçãO DE RáDIO". Um comparador de valor SIR alvo 116 compara um valor SIR alvo retido por um retentor de valor SIR alvo 110 com um valor limite retido por um retentor de valor limite SIR alvo 115, e envia um resultado da comparação para um seletor de código de dispersão 117. O seletor de código de dispersão 117 determina um código de dispersão a ser utilizado por um aparelho de terminal de comunicação com base no resultado da comparação, e envia um resultado determinado para uma seção de estruturação de quadro 111 e para o de-dispersor 104 como uma informação de dispersão. A seção estruturada de quadro 111 envia a informação de transmissão que tem a informação do código de dispersão adicionada para um modulador 112. O de-dispersor 104 fornece um processamento de de-dispersão para um sinal recebido utilizando um código de dispersão reconhecido utilizando a informação de código de dispersão.
