<p><P>PROBLEM TO BE SOLVED: To provide a wireless communication apparatus which improves the sound quality of recording without greatly increasing a necessary storage capacity for recording even if a fault on the wireless network is superposed. <P>SOLUTION: When operating as a receiver, a receiving unit 10 outputs hard decision/reliability information Aa made of hard decision information added with reliability information that is multi-valued data based on input signal from a radio line; an error correction decoder 9 receives it to apply a decoding processing; subsequently, a sound decoder 8 applies sound decoding to it; a D/A conversion unit 7 applies D/A conversion; and finally a sound output unit 6 outputs it as sound. When recording sound, the hard decision/reliability information Aa output from the receiving unit 10 is recorded in a sound recording unit 12. When the sound recording information recorded in the recording unit 12 is replayed, the hard decision/reliability information Aa recorded in the recording unit 12 is read out, supplied as replay signal R to the error correction decoder 9, applied with processing in and after the error correction decoding, and then output as sound from a sound output unit 6. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
