FIG. 12 is a schematic block diagram showing processes for processing the data according to the sixth embodiment of the present disclosure. As compared with FIG. 11, in FIG. 12, the five processes 301?305 and the process of symbol permutation 313 are unchanged, but a process of repetition 314 is newly added between the process of modulation 304 and the process of symbol permutation 313. Specifically, as shown in FIG. 11, n symbols s1, s2, . . . , sn obtained after the process of modulation 304 are repeated into n*N symbols s1, s2, . . . , sn*N in the process of repetition 314. Then, these n*N symbols s1, s2, . . . , sn*N are performed symbol permutation by using different symbol permutation patterns for different repetition levels in the process of symbol permutation 313. Finally, n*N symbols after symbol permutation are mapped onto N subframes by the process of RE mapping 305 as shown in FIG. 12.
In FIG. 11, n symbols which are finally mapped onto one subframe are performed the symbol permutation. In FIG. 12, n*N symbols which are finally mapped onto N subframes are performed the symbol permutation. Thus, it can be seen that the symbol permutation may happens within symbols which are finally mapped onto one subframe or may be happens within symbols which are finally mapped onto more than one subframes.
