ABSTRACT:
A wireless transmitting apparatus capable of improving the reception characteristic at a data stream receiving end. In this apparatus, I/Q separating parts (110, 112) each separate first data modulated symbols included in any of a plurality of data streams, which are to be multiplexed, into first in-phase components and first orthogonal components, while separating second data modulated symbols included in the other ones of the plurality of data streams into second in-phase components and second orthogonal components. An I/Q converting part (114) converts the first in-phase components to third orthogonal components, while converting the second orthogonal components to fourth in-phase components. A multi-code multiplexing part multi-code multiplexes the first and third orthogonal components to provide a first multiplexed signal, while multi-code multiplexing the second and fourth in-phase components to provide a second multiplexed signal. An I/Q combining part (124) combines the first and second multiplexed signals to provide a combined signal.
