| Abstract(in English) | OFDM signals consist of independent subcarriers, and high peak-to-average power ratio(PAPR). PAPR should be suppressed for the efficient amplification of OFDM, because it produces the nonlinear distortion at the amplifier output. In this paper, we prornse a new method which suppresses PAPR of OFDM by the phase shift of rotationally invariant Trellis Coded Modulation(TCM). Numerical results of 8-subcarrier OFDM show that the method reduces PAPR to 8.45[dB]by the phase shift of single subcarrier, and to 7.78[dB] by that of two subcarriers. |
