V2V (Vehicle-to-Vehicle) communication has attracted attention to realize cooperative automated vehicles. In IEEE 802.11p, which standardizes physical and MAC layer specifications of V2V communication, broadcast CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) is adopted as an access control scheme. CSMA/CA is a protocol that avoids collision in a distributed manner by carrier sensing and controlling the transmission timing of each node. However, when communication traffic increases, multiple signals from multiple vehicles collide and thus communication reliability decreases [1]. One of the solutions to this problem is simultaneous transmission and SIC (Successive Interference Cancellation), which is widely studied as a technique to enable receivers to demodulate multiple signals from a mixed signal [2]. However, SIC is not successful when the difference of the received power between signals in a mixed signal is small, e.g. when the hidden node problem occurs. On the other hand, diversity techniques such as multi-antenna system are widely used to mitigate collision caused by the hidden node problem and channel fluctuation caused by fading. Multi-antenna systems decrease PER (Packet Error Rate) by selecting and/or combining the multiple received signals.
