In this paper, we investigate performance of partial transmit sequence (PTS) for peak-to-average-power(PAPR) reduction in orthogonal frequency division multiplexing with index modulation (OFDM-IM), where three patterns of subcarrier grouping are considered. Firstly, the PAPR performance in terms of the independence of candidate sequences generated by three subcarrier grouping patterns are analyzed, respectively. Both theoretical analysis and numeric simulation show that PTS can achieve somewhat better PAPR performance in OFDM-IM than that in OFDM system. Moreover, the issue of imperfect side information(SI) at the receiver is investigated for exposing the relationship between SI transmitting scheme and BER performance. In the context, the comparison of OFDM and OFDM-IM signal shows that the BER performance of PTS aided OFDM-IM is more robust than that of OFDM signal.
