Abstract: Method for generating a built-symbol including plurality of sub-symbols for transmission including data of an original symbol of an orthogonal multi-carrier modulation-signal reducing the peak-to-average power-ratio (PAPR) and increase its robustness against Doppler-effects of the orthogonal multi-carrier modulation-signal, the original symbol lasting a duration, Ts and carried by N-tones; also including: applying intrinsic temporal diversity properties of complex N-points Inverse-Fast-Fourier-Transform to the original symbol, where plurality of sub-symbols number is M, each M sub-symbols lasts Ts/M and is carried by N/M disjoint-tones, the M sub-symbols are time-multiplexed, so the time-multiplexed built-symbol contains all-data at the same rate of the original symbol. The built-symbol is demodulated, utilizing an orthogonal multi-carrier receiver.
