Abstract
There is a problem that if a transmitter apparatus having an adaptive modulation function is to be configured to divide data for transmission, the structure of the transmitter apparatus will be complicated and the cost thereof will be raised. In order to solve this problem, a transmitter apparatus comprises: a dividing means for dividing input data into a plurality of pieces of data; a plurality of transmitting means for transmitting the pieces of data as divided to respective transmission paths; and a modulation scheme deciding means for deciding, from among modulation schemes associated with the conditions of the transmission paths, a modulation scheme, which is to be used by the transmission means, such that the difference in transmission speed between the pieces of data transmitted by the plurality of transmitting means is within a predetermined range.
