MULTICARRIER TRANSMISSION SYSTEM AND MULTICARRIER TRANSMISSION METHOD |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To improve transmission quality by suppressing inter-code interference due to the influence of a frequency selective transmission line in a system for performing multicarrier transmission by code spreading. <P>SOLUTION: On the basis of a receiving power spectrum in each subcarrier, data subcarriers in the same spread code band are mapped in a subcarrier group in which the dispersion of receiving power spectra is small. <P>COPYRIGHT: (C)2007,JPO&INPIT |
