Relaying is a power-efficient technique to guarantee runiform coverage in cellular systems for areas where
the direct link from the base station (BS) is weak, e.g., cell
edge and deep shadow fading areas [1] [2]. With no need of
any wired backhaul from the BS, this cost-effective technique
has been incorporated into several wireless communication
standards, including 3GPP LTE-Advanced and IEEE 802.16,
and is expected to be deployed extensively in the upcoming
5G systems [3] [4] as well as infrastructure-based vehicular
networks [5]. To avoid self interference (SI) from its own transmitter,
traditional relay works in half-duplex mode, resulting
in up to 50% spectral efficiency loss, which severely limits its
realistic applications. In recent years, due to the advances of
SI cancellation techniques [6], full-duplex relaying (FDR), that
can recover the spectral efficiency loss of half-duplex relaying
