Abstract

Un receptor de señal OFDM (30) incluye: una unidad de recepción (31) que es configurada para realizar un proceso de recepción en una señal recibida OFDM para cada tiempo de longitud de símbolo OFDM; una pluralidad de unidades de desintercalado (341,... 34n) configurada de modo que realice un proceso de intercalado en los datos adquiridos por el proceso de recepción en una unidad de bloque de intercalado; y una pluralidad de unidades de decodificación (361 a 36n) configurada para realizar un proceso de decodificación en los datos salidos a partir de las unidades de desintercalado (341 a 34n). El bloque de intercalado es una parte de un bloque de intervalo de tiempo de transmisión formado por los datos transmitidos en cada intervalo de transmisión.
