The 3rd Generation Partnership Project (3GPP) has recently developed device-to-device (D2D) communication to cope with the explosively increasing mobile data traffic.

• The D2D communication uses sidelink that is based on the single carrier-frequency division multiple access (SC-FDMA) scheme because of its low peak-to-average power ratio (PAPR) [Myung, H. G., Lim, J., & Goodman, D. J. (2006). Single carrier FDMA for uplink wireless transmission. IEEE Vehicular Technology Magazine, 1(3), 30–38].
• In addition, the demodulation reference signal (DMRS) is designed to support multiple input multiple output.
