This letter proposes a modified orthogonal frequency division multiplexing (OFDM) signal with low peak-to-average power ratio (PAPR). As the case of previous works, OFDM system exploits a frequency diversity by using a simple symbol repetition. From the presented results, we can see that three modified OFDM signals using one transmit antenna can be implemented with low PAPR, still maintaining the same diversity gain at the receiver as in [9],[10].
