| 摘要 |
The invention concerns a method for generating a built symbol for transmission comprising data of an original symbol of an orthogonal multi-carrier modulation signal in order to reduce the peak-to-average power ratio (PAPR) of the orthogonal multi-carrier modulation signal, the original symbol lasting for a duration T S and carried by N tones; the method comprising: partitioning the N tones into M tone sub-sets respectively comprising N/M tones; for each of the M tone sub-sets, generating by the intrinsic temporal-diversity property of Fast Fourier Transform a corresponding candidate sub-symbol set comprising M sub-symbols, each sub-symbol lasting for a duration Ts/M and carried by the N/M tones of the corresponding tone sub-sets; selecting from each of the M candidate sub-symbol sets a sub-symbol, wherein any two of the selected sub-symbols contain two different data; generating the built symbol for transmission comprising the M selected sub-symbols so that the built symbol contains all the data of the original symbol. |
