<P>PROBLEM TO BE SOLVED: To suppress power consumption with a compact size while suppressing the deterioration of modulation accuracy and a bit error rate. <P>SOLUTION: A pre-emphasis unit 11 performs pre-emphasis processing upon a signal for radio transmission. A clip unit 12 performs amplitude limitation upon the pre-emphasized signal by the pre-emphasis unit 11, with a predetermined threshold. A de-emphasis unit 14 performs de-emphasis processing upon the signal on which amplitude limitation is made by the clip unit 12. A frequency conversion unit 15 performs frequency conversion on the signal, on which the de-emphasis processing is made by the de-emphasis unit 14, to perform radio transmission. <P>COPYRIGHT: (C)2013,JPO&INPIT |
