Wireless relaying is a promising strategy in current and future communication systems to enable reliable transmission and broad coverage for a variety of applications. In conventional wireless multiuser networks, highly reliable data transmission is not guaranteed between the access point and the mobile users that are located in geographically remote areas. To overcome this problem, a relay can be introduced to ensure effective communication between the two ends. This is referred to as multiuser relay networks - a viable option for emerging technologies such as IEEE 802.16j multi-hop relay networks and IEEE 802.11s mesh networks.
