先前的工作已经完成在[1],[2],[3],[4],其重点是系统级描述的用户合作的概念。它专注于物理层问题,任何的期待更高层次的开销将收益相比可以忽略不计。重点合作的类型,是活跃用户的合作,即。用户信息的发送,因此不想仅仅是另一个用户的继电器。合作转发是一种有效的技术来对抗多径衰落,提高系统容量,提高覆盖率。最初,高斯中继信道容量分析是全面研究[6]。对于网络场景,在[7]能力进行了分析。编码策略,利用节点合作开发为继电器网络[8]。停机的概率种放大和转发中继系统分析了[9]。在[10],封闭形式表达平均误比特率、衰落和中断概率推导了Rayleighfading通道继电器工作的地方在非再生模式和目标执行等增益组合。 An overview of various cooperation schemes and issues related to their implementation has been discussed in [11]. Various power allocation strategies for non-generative relay network have been studied in [12]. In [13], closed form expressions of outage probability and bit error rate (BER) for binary phase shift keying (BPSK) are derived for the case where communication between source and destination is supported by multi antenna relay and both relay and destination perform maximum ratio combining (MRC) of signals in Rayleigh fading channel. Outage probability and average error rate of two-hop multi antenna relay based system for the case when relay performs selection combining (SC) of signals and destination performs MRC of signals are analyzed in [14] and [15], respectively. Closed form expressions of BER have been established in [16] for two-hop multi antenna cooperative relay network in Rayleigh fading channel. Here, destination performs selection combining of signals received from source, relay and relay performs selection or MRC combining of signal. In [17], analytical expressions of average received SNR, outage BER and channel capacity has been established for the case when source and relay are communicating with multi-antenna destination in Rayleigh fading channel. Closed form expression of outage probability has been derived in [18]; here, communication between source and destination is supported by two multi-antenna relay nodes.
