Abstract

APARELHO DE COMUNICAçãO DE MULTIPORTADORA E MéTODO DE COMUNICAçãO DE MULTIPORTADORA. A presente invenção refere-se a um aparelho de comunicação de multiportadora e similar em que a quantidade aritmética requerida para calcular um peso de recepção pelo qual um sinal de multiportadora deve ser multiplicado que é suprimido, enquanto a característica de recepção para o sinal de multiportadora é aperfeiçoada. No aparelho, uma parte de geração de peso de transmissão de subportadora (513) gera um peso de transmissão de cada subportadora, com base em informação de canal de cada subportadora recebida de uma parte de geração de informação de canal (511) e um peso de recepção de cada grupo de subportadoras recebido de uma parte de geração de peso de recepção de grupo de subportadoras (512). A parte de geração de peso de transmissão de subportadora (513) introduz os pesos de transmissão gerados das respectivas subportadoras para os correspondentes dos multiplicadores (522).
