摘要
协作分集是一种新的空域分集,两个以上单天线移动终端通过中继彼此的信息,共享彼此的天线形成虚拟天线阵列,获得传输分集.协作分集可以像MIMO系统一样提升系统容量,增大数据传输速率,有效对抗衰落以及降低系统的服务中断概率,提高系统的服务质量和可靠性等.
Cooperative diversity is a new kind of space diversity, two or more mobile terminals with single antenna relay information for each other, thus, virtual mobile antenna array is formed, and transmitting diversity is achieved. Various results show that cooperative diversity can increase the capacity of communication system, increase the data transmission rate, resist fading effectively, lower the outage probability of service, and increase the quality of service and reliability.
