<p><P>PROBLEM TO BE SOLVED: To provide a multi-carrier transmission apparatus which avoids the error due to nonstationary noises at transmitting data needing a high speed response, thereby ensuring the stability of the high response. <P>SOLUTION: The apparatus comprises frequency band sorting means (corresponding to frequency band sorters 3122, 4102) for sorting an operating frequency band for the data transmission into a stationary frequency band with stationary noises and a nonstationary frequency band with nonstationary noises, and data transmitting means (corresponding to mappers 302, 402 and demappers 307, 406) for transmitting data needing the high speed response allotted to carriers corresponding to the stationary frequency band. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
