Radio Transmitting Apparatus, Radio Receiving Apparatus, Radio Transmitting Method and Radio Receiving Method

摘要

A radio transmitting apparatus and the like for improving the reception error rate characteristic. In this apparatus, a data modulating part ( 121 ) modulates a data signal to provide a modulated symbol. A Q-inverting part ( 125 ) generates a symbol that corresponds to the modulated symbol provided by the data modulating part ( 121 ) and that, when combined with the modulated symbol, becomes a signal having a particular value. A multiplexing part ( 110 ) multiplexes the modulated symbol provided by the data modulating part ( 121 ) with the corresponding symbol generated by the Q-inverting part ( 125 ) to provide a multiplexed signal.
