Abstract
A MIMO multiple transmission device, comprising a packet data block generator () for generating a packet data block as a resent unit for hybrid ARQ; a CRC adder () for adding an error detection code; a channel encoder () for performing channel encoding, the packet data block generator, the CRC adder and the channel encoder being coupled in series in one or more data streams; a parallel-to-serial converter () for converting output of the channel encoder to serial form; an interleaver between transmission streams () for performing interleaving between transmission streams on outputs from the parallel-to-serial converter; a serial-to-parallel converter () for converting outputs from the interleaver between transmission streams to parallel form; a coding rate changer () for changing a coding rate; and a data modulator () for modulating data, the coding rate changer and the data modulator being connected in series in plural data streams divided by the serial-to-parallel converter.
