ABSTRACT:
A wireless communication apparatus capable of suppressing the reduction in the error correction ability in the wireless communication apparatus at the receiving end even when the propagation path environment is bad and hence the reception quality of received signals is low. This apparatus comprises a turbo encoding part (111) for performing an error correction encoding of transport data; a modulating part (113) for modulating the transport data as error correction coded to generate a modulated signal; a modulation diversity modulating part (120) for generating a modulation diversity modulated signal from the modulated signal; an S/P part (133) for generating a transport signal from one of the modulated signal and the modulation diversity modulated signal; and a deciding part (112) for deciding, in accordance with the propagation path environment of the transport signal as wireless transmitted, from which the transport signal is generated by the S/P part (133), the modulated signal or the modulation diversity modulated signal.
