PURPOSE:To make the scale of a transmitter small by reducing number of time division multiplexers so as to simplify the configuration of the hardware. CONSTITUTION:Transmission data are subject to orthogonal transformation by orthogonal transformation devices 31-34 at a base band. Connection control data are gathered by each integral number not in excess of a ratio of transmission data and the connection control data and subject to time division multiplex processing by a multiplexer 20 and multiplexed data are subject to orthogonal transformation by an orthogonal transformation device 35 at a base band. The base band data subject to orthogonal transformation by the orthogonal transformation devices 31-35 are added by an adder 40 and carrier-modulated by a radio equipment 50 and sent as a radio wave through an antenna 60. |
