“…As SC-FDMA is an OFDM-based technique, GLPSM requires as many RF chains as the transmit antennas, i.e., N T [16]. Hence, there are N T output amplifiers and all transmit antennas are simultaneously active.…”

“…Hence, there are N T output amplifiers and all transmit antennas are simultaneously active. In analogy to [16], GLPSM coding in SC-FDMA is implemented as a multiplication of QAM/PSK symbol with the corresponding coding coefficients for all transmit antennas. Unlike the conventional SM, all QAM/PSK symbols are transmitted via all transmit antennas simultaneously and the additional spatial bits are not in the index of the active transmit antenna, but in the coding coefficients of all antennas.…”

“…The main constraint is that the PAPR level has to be preserved. As it has been shown in [16], the low PAPR condition in SC-FDMA requires that all transmit antennas are active all the time. Therefore, the conclusions from GSM cannot be applied in the same manner to LPSM as a subset of active transmit antennas cannot be used.…”

“…Recently, in [16], it has been shown that the conventional SM is not suitable for SC-FDMA as it increases PAPR and low PAPR SM (LPSM) has been proposed. The cases of two and four transmit antennas have been studied and it has been shown that LPSM shows good performances in different channel models for different receivers while maintaining low PAPR level on all transmit antennas.…”

The main reason for the selection of single-carrier frequency division multiple access (SC-FDMA) modulation technique in mobile high data rate communications lays in its low value of peak-to-average power ratio (PAPR). If spatial modulation, a multiple-input multiple-output technique that achieves bitrate increase, is applied to the SC-FDMA system in its conventional form, the PAPR level is increased. Hence, based on previously mentioned, in this paper, we provide the general design criteria for low PAPR spatial modulation (LPSM) implemented in SC-FDMA systems with multiple transmit antennas. The straightforward generalization of LPSM is derived and it is shown that it requires the number of transmit antennas to be doubled in order to add another bit in the spatial component. Based on that, the alternative generalized technique with higher number of spatial bits is proposed. As these techniques present single-stream generalizations, the approach with multiple-streams is proposed as well. After PAPR and performance comparisons, it is concluded that single-stream techniques outperform multiple-stream techniques in the cases of low overall data rate, whereas multiple-stream approach is better in high overall data rate scenarios. All proposed techniques maintain low PAPR level on all transmit antennas.

SummaryThis paper proposes a new method for reducing the peak-to-average power ratio of the single-carrier frequency-division multiple access system. The method is an integration of the tone injection (TI) and tone reservation (TR) techniques.A recommended method that uses TI to improve TR's low data transmission rate problem that is caused by the reservation of subcarriers. Additionally, to reduce the massive amount of computation required by the combined needs of TI and TR, an iterative flipping algorithm was adopted for this purpose. Simulation results indicate that the proposed method is not only capable of effectively improving the peak-to-average power ratio-reduction efficiency of the single-carrier frequency-division multiple access system but it can also improve the data transmission rate of the conventional TR technique.
