Abstract

an input data transform means to store information inputted in parallel by constructing a set in data bit number of one symbol to be transmitted to each sub channel and to output data set bn corresponding to each sub channel; a first selection means to output by selecting data set bn corresponding to each sub channel one by one; a signal mapper to arrange data set bn selected by the first selection means as a signal on N multiple dimension; a second selection means to output by selecting the output of the signal mapper by synchronizing with the first selection means; an output data transform means; a control means to control each means to operate by inputting transmission symbol period, maximum transmission capacity of each sub channel and the specified multiple dimension number; a modulation means to modulate 2 dimensional symbol outputted from the output data transform means; and a synthesis means to form multiple carrier by synthesizing the signals outputted from the modulation means.
