Receiver and method for decoding a coded signal with the aid of a space-time or space-frequency coding matrix

The present invention is repeatedly equipped with space, a time decoding step, and at least two about the method for decoding a received signal equipped with the symbol distributed at space and time by space and a time code procession, and this each is related with a method equipped with the following sub steps. A diversity プリデ code contrary to the diversity プリデ code executed at the time of the discharge of a signal which offers プリコード data is performed. The symbol which forms the above-mentioned signal is presumed based on the above-mentioned プリデ code data, and a presumed symbol is offered. In order to offer estimation signals, the same diversity プリコード as diversity プリコード executed at the time of the discharge applied to the presumed symbol is performed.
