Apparatus and method for transmitting information, utilizing a multicarrier waveform containing the information. The waveform presents symmetrically-shaped first and second sequential portions which are substantially equal in length. All subcarriers are restricted in phase values to 0 and π, or alternatively, π/2 and 3π/2. One, but not both, of the portions is transmitted to a receiver. The transmitted portion is duplicated and the duplicated portion is than reversed. The duplicated portion is also inverted in the case where the phase values are restricted to 0 and π. The duplicated, processed portion is then sequentially combined with the originally transmitted portion to reform substantially the original waveform. Thus the invention dramatically reduces the length of the waveform to be transmitted, thereby increasing transmission and reception rates while minimizing the number of calculations required.
